Changelog for openssh-helpers-8.9p1-1.1.x86_64.rpm :

* Mon Aug 08 2022 Thorsten Kukuk - Use %_pam_vendordir
* Wed Jul 06 2022 Adam Majer - openssh-8.4p1-ssh_config_d.patch: admin overrides should take priority (listed first) over package defaults
* Mon Mar 28 2022 Ludwig Nussel - read ssh and sshd config file also from /usr/etc- add openssh-server-config-rootlogin subpackage that enabled PermitRootLogin
* Mon Mar 07 2022 Hans Petter Jansson - Version update to 8.9p1: = Security
* sshd(8): fix an integer overflow in the user authentication path that, in conjunction with other logic errors, could have yielded unauthenticated access under difficult to exploit conditions. This situation is not exploitable because of independent checks in the privilege separation monitor. Privilege separation has been enabled by default in since openssh-3.2.2 (released in 2002) and has been mandatory since openssh-7.5 (released in 2017). Moreover, portable OpenSSH has used toolchain features available in most modern compilers to abort on signed integer overflow since openssh-6.5 (released in 2014). Thanks to Malcolm Stagg for finding and reporting this bug. = Potentially-incompatible changes
* sshd(8), portable OpenSSH only: this release removes in-built support for MD5-hashed passwords. If you require these on your system then we recommend linking against libxcrypt or similar.
* This release modifies the FIDO security key middleware interface and increments SSH_SK_VERSION_MAJOR. = New features
* ssh(1), sshd(8), ssh-add(1), ssh-agent(1): add a system for restricting forwarding and use of keys added to ssh-agent(1) A detailed description of the feature is available at https://www.openssh.com/agent-restrict.html and the protocol extensions are documented in the PROTOCOL and PROTOCOL.agent files in the source release.
* ssh(1), sshd(8): add the sntrup761x25519-sha512AATTopenssh.com hybrid ECDH/x25519 + Streamlined NTRU Prime post-quantum KEX to the default KEXAlgorithms list (after the ECDH methods but before the prime-group DH ones). The next release of OpenSSH is likely to make this key exchange the default method.
* ssh-keygen(1): when downloading resident keys from a FIDO token, pass back the user ID that was used when the key was created and append it to the filename the key is written to (if it is not the default). Avoids keys being clobbered if the user created multiple resident keys with the same application string but different user IDs.
* ssh-keygen(1), ssh(1), ssh-agent(1): better handling for FIDO keys on tokens that provide user verification (UV) on the device itself, including biometric keys, avoiding unnecessary PIN prompts.
* ssh-keygen(1): add \"ssh-keygen -Y match-principals\" operation to perform matching of principals names against an allowed signers file. To be used towards a TOFU model for SSH signatures in git.
* ssh-add(1), ssh-agent(1): allow pin-required FIDO keys to be added to ssh-agent(1). $SSH_ASKPASS will be used to request the PIN at authentication time.
* ssh-keygen(1): allow selection of hash at sshsig signing time (either sha512 (default) or sha256).
* ssh(1), sshd(8): read network data directly to the packet input buffer instead of indirectly via a small stack buffer. Provides a modest performance improvement.
* ssh(1), sshd(8): read data directly to the channel input buffer, providing a similar modest performance improvement.
* ssh(1): extend the PubkeyAuthentication configuration directive to accept yes|no|unbound|host-bound to allow control over one of the protocol extensions used to implement agent-restricted keys. = Bugfixes
* sshd(8): document that CASignatureAlgorithms, ExposeAuthInfo and PubkeyAuthOptions can be used in a Match block. PR277.
* sshd(8): fix possible string truncation when constructing paths to .rhosts/.shosts files with very long user home directory names.
* ssh-keysign(1): unbreak for KEX algorithms that use SHA384/512 exchange hashes
* ssh(1): don\'t put the TTY into raw mode when SessionType=none, avoids ^C being unable to kill such a session. bz3360
* scp(1): fix some corner-case bugs in SFTP-mode handling of ~-prefixed paths.
* ssh(1): unbreak hostbased auth using RSA keys. Allow ssh(1) to select RSA keys when only RSA/SHA2 signature algorithms are configured (this is the default case). Previously RSA keys were not being considered in the default case.
* ssh-keysign(1): make ssh-keysign use the requested signature algorithm and not the default for the key type. Part of unbreaking hostbased auth for RSA/SHA2 keys.
* ssh(1): stricter UpdateHostkey signature verification logic on the client- side. Require RSA/SHA2 signatures for RSA hostkeys except when RSA/SHA1 was explicitly negotiated during initial KEX; bz3375
* ssh(1), sshd(8): fix signature algorithm selection logic for UpdateHostkeys on the server side. The previous code tried to prefer RSA/SHA2 for hostkey proofs of RSA keys, but missed some cases. This will use RSA/SHA2 signatures for RSA keys if the client proposed these algorithms in initial KEX. bz3375
* All: convert all uses of select(2)/pselect(2) to poll(2)/ppoll(2). This includes the mainloops in ssh(1), ssh-agent(1), ssh-agent(1) and sftp-server(8), as well as the sshd(8) listen loop and all other FD read/writability checks. On platforms with missing or broken poll(2)/ppoll(2) syscalls a select(2)-based compat shim is available.
* ssh-keygen(1): the \"-Y find-principals\" command was verifying key validity when using ca certs but not with simple key lifetimes within the allowed signers file.
* ssh-keygen(1): make sshsig verify-time argument parsing optional
* sshd(8): fix truncation in rhosts/shosts path construction.
* ssh(1), ssh-agent(1): avoid xmalloc(0) for PKCS#11 keyid for ECDSA keys (we already did this for RSA keys). Avoids fatal errors for PKCS#11 libraries that return empty keyid, e.g. Microchip ATECC608B \"cryptoauthlib\"; bz#3364
* ssh(1), ssh-agent(1): improve the testing of credentials against inserted FIDO: ask the token whether a particular key belongs to it in cases where the token supports on-token user-verification (e.g. biometrics) rather than just assuming that it will accept it. Will reduce spurious \"Confirm user presence\" notifications for key handles that relate to FIDO keys that are not currently inserted in at least some cases. bz3366
* ssh(1), sshd(8): correct value for IPTOS_DSCP_LE. It needs to allow for the preceding two ECN bits. bz#3373
* ssh-keygen(1): add missing -O option to usage() for the \"-Y sign\" option.
* ssh-keygen(1): fix a NULL deref when using the find-principals function, when matching an allowed_signers line that contains a namespace restriction, but no restriction specified on the command-line
* ssh-agent(1): fix memleak in process_extension(); oss-fuzz issue #42719
* ssh(1): suppress \"Connection to xxx closed\" messages when LogLevel is set to \"error\" or above. bz3378
* ssh(1), sshd(8): use correct zlib flags when inflate(3)-ing compressed packet data. bz3372
* scp(1): when recursively transferring files in SFTP mode, create the destination directory if it doesn\'t already exist to match scp(1) in legacy RCP mode behaviour.
* scp(1): many improvements in error message consistency between scp(1) in SFTP mode vs legacy RCP mode.
* sshd(8): fix potential race in SIGTERM handling PR289
* ssh(1), ssh(8): since DSA keys are deprecated, move them to the end of the default list of public keys so that they will be tried last. PR295
* ssh-keygen(1): allow \'ssh-keygen -Y find-principals\' to match wildcard principals in allowed_signers files = Portability
* ssh(1), sshd(8): don\'t trust closefrom(2) on Linux. glibc\'s implementation does not work in a chroot when the kernel does not have close_range(2). It tries to read from /proc/self/fd and when that fails dies with an assertion of sorts. Instead, call close_range(2) directly from our compat code and fall back if that fails. bz#3349,
* OS X poll(2) is broken; use compat replacement. For character- special devices like /dev/null, Darwin\'s poll(2) returns POLLNVAL when polled with POLLIN. Apparently this is Apple bug 3710161 - not public but a websearch will find other OSS projects rediscovering it periodically since it was first identified in 2005.
* Correct handling of exceptfds/POLLPRI in our select(2)-based poll(2)/ppoll(2) compat implementation.
* Cygwin: correct checking of mbstowcs() return value.
* Add a basic SECURITY.md that refers people to the openssh.com website.
* Enable additional compiler warnings and toolchain hardening flags, including -Wbitwise-instead-of-logical, -Wmisleading-indentation, - fzero-call-used-regs and -ftrivial-auto-var-init.
* HP/UX. Use compat getline(3) on HP-UX 10.x, where the libc version is not reliable.- Rebased patches:
* openssh-7.7p1-ldap.patch
* openssh-8.0p1-gssapi-keyex.patch
* openssh-8.1p1-audit.patch
* openssh-8.4p1-vendordir.patch
* openssh-reenable-dh-group14-sha1-default.patch
* Tue Sep 28 2021 Hans Petter Jansson - Version update to 8.8p1: = Security
* sshd(8) from OpenSSH 6.2 through 8.7 failed to correctly initialise supplemental groups when executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive has been set to run the command as a different user. Instead these commands would inherit the groups that sshd(8) was started with. Depending on system configuration, inherited groups may allow AuthorizedKeysCommand/AuthorizedPrincipalsCommand helper programs to gain unintended privilege. Neither AuthorizedKeysCommand nor AuthorizedPrincipalsCommand are enabled by default in sshd_config(5). = Potentially-incompatible changes
* This release disables RSA signatures using the SHA-1 hash algorithm by default. This change has been made as the SHA-1 hash algorithm is cryptographically broken, and it is possible to create chosen-prefix hash collisions for * ssh(1): allow the ssh_config(5) CanonicalizePermittedCNAMEs directive to accept a \"none\" argument to specify the default behaviour. = Bugfixes
* scp(1): when using the SFTP protocol, continue transferring files after a transfer error occurs, better matching original scp/rcp behaviour.
* ssh(1): fixed a number of memory leaks in multiplexing,
* ssh-keygen(1): avoid crash when using the -Y find-principals command.
* A number of documentation and manual improvements, including bz#3340, PR139, PR215, PR241, PR257- Additional changes from 8.7p1 release: = Potentially-incompatible changes
* scp(1): this release changes the behaviour of remote to remote copies (e.g. \"scp host-a:/path host-b:\") to transfer through the local host by default. This was previously available via the -3 flag. This mode avoids the need to expose credentials on the origin hop, avoids triplicate interpretation of filenames by the shell (by the local system, the copy origin and the destination) and, in conjunction with the SFTP support for scp(1) mentioned below, allows use of all authentication methods to the remote hosts (previously, only non-interactive methods could be used). A -R flag has been added to select the old behaviour.
* ssh(1)/sshd(8): both the client and server are now using a stricter configuration file parser. The new parser uses more shell-like rules for quotes, space and escape characters. It is also more strict in rejecting configurations that include options lacking arguments. Previously some options (e.g. DenyUsers) could appear on a line with no subsequent arguments. This release will reject such configurations. The new parser will also reject configurations with unterminated quotes and multiple \'=\' characters after the option name.
* ssh(1): when using SSHFP DNS records for host key verification, ssh(1) will verify all matching records instead of just those with the specific signature type requested. This may cause host key verification problems if stale SSHFP records of a different or legacy signature type exist alongside other records for a particular host. bz#3322
* ssh-keygen(1): when generating a FIDO key and specifying an explicit attestation challenge (using -Ochallenge), the challenge will now be hashed by the builtin security key middleware. This removes the (undocumented) requirement that challenges be exactly 32 bytes in length and matches the expectations of libfido2.
* sshd(8): environment=\"...\" directives in authorized_keys files are now first-match-wins and limited to 1024 discrete environment variable names. = New features
* scp(1): experimental support for transfers using the SFTP protocol as a replacement for the venerable SCP/RCP protocol that it has traditionally used. SFTP offers more predictable filename handling and does not require expansion of glob(3) patterns via the shell on the remote side.
* sftp-server(8): add a protocol extension to support expansion of ~/ and ~user/ prefixed paths. This was added to support these paths when used by scp(1) while in SFTP mode.
* ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to the ssh(1) -f flag. GHPR231
* ssh(1): add a StdinNull directive to ssh_config(5) that allows the config file to do the same thing as -n does on the ssh(1) command- line. GHPR231
* ssh(1): add a SessionType directive to ssh_config, allowing the configuration file to offer equivalent control to the -N (no session) and -s (subsystem) command-line flags. GHPR231
* ssh-keygen(1): allowed signers files used by ssh-keygen(1) signatures now support listing key validity intervals alongside they key, and ssh-keygen(1) can optionally check during signature verification whether a specified time falls inside this interval. This feature is intended for use by git to support signing and verifying objects using ssh keys.
* ssh-keygen(8): support printing of the full public key in a sshsig signature via a -Oprint-pubkey flag. = Bugfixes
* ssh(1)/sshd(8): start time-based re-keying exactly on schedule in the client and server mainloops. Previously the re-key timeout could expire but re-keying would not start until a packet was sent or received, causing a spin in select() if the connection was quiescent.
* ssh-keygen(1): avoid Y2038 problem in printing certificate validity lifetimes. Dates past 2^31-1 seconds since epoch were displayed incorrectly on some platforms. bz#3329
* scp(1): allow spaces to appear in usernames for local to remote and scp -3 remote to remote copies. bz#1164
* ssh(1)/sshd(8): remove references to ChallengeResponseAuthentication in favour of KbdInteractiveAuthentication. The former is what was in SSHv1, the latter is what is in SSHv2 (RFC4256) and they were treated as somewhat but not entirely equivalent. We retain the old name as a deprecated alias so configuration files continue to work as well as a reference in the man page for people looking for it. bz#3303
* ssh(1)/ssh-add(1)/ssh-keygen(1): fix decoding of X.509 subject name when extracting a key from a PKCS#11 certificate. bz#3327
* ssh(1): restore blocking status on stdio fds before close. ssh(1) needs file descriptors in non-blocking mode to operate but it was not restoring the original state on exit. This could cause problems with fds shared with other programs via the shell, bz#3280 and GHPR246
* ssh(1)/sshd(8): switch both client and server mainloops from select(3) to pselect(3). Avoids race conditions where a signal may arrive immediately before select(3) and not be processed until an event fires. bz#2158
* ssh(1): sessions started with ControlPersist were incorrectly executing a shell when the -N (no shell) option was specified. bz#3290
* ssh(1): check if IPQoS or TunnelDevice are already set before overriding. Prevents values in config files from overriding values supplied on the command line. bz#3319
* ssh(1): fix debug message when finding a private key to match a certificate being attempted for user authentication. Previously it would print the certificate\'s path, whereas it was supposed to be showing the private key\'s path. GHPR247
* sshd(8): match host certificates against host public keys, not private keys. Allows use of certificates with private keys held in a ssh-agent. bz#3524
* ssh(1): add a workaround for a bug in OpenSSH 7.4 sshd(8), which allows RSA/SHA2 signatures for public key authentication but fails to advertise this correctly via SSH2_MSG_EXT_INFO. This causes clients of these server to incorrectly match PubkeyAcceptedAlgorithmse and potentially refuse to offer valid keys. bz#3213
* sftp(1)/scp(1): degrade gracefully if a sftp-server offers the limitsAATTopenssh.com extension but fails when the client tries to invoke it. bz#3318
* ssh(1): allow ssh_config SetEnv to override $TERM, which is otherwise handled specially by the protocol. Useful in ~/.ssh/config to set TERM to something generic (e.g. \"xterm\" instead of \"xterm-256color\") for destinations that lack terminfo entries.
* sftp-server(8): the limitsAATTopenssh.com extension was incorrectly marked as an operation that writes to the filesystem, which made it unavailable in sftp-server read-only mode. bz#3318
* ssh(1): fix SEGV in UpdateHostkeys debug() message, triggered when the update removed more host keys than remain present.
* Many manual page fixes.- Additional changes from 8.6p1 release: = Security
* sshd(8): OpenSSH 8.5 introduced the LogVerbose keyword. When this option was enabled with a set of patterns that activated logging in code that runs in the low-privilege sandboxed sshd process, the log messages were constructed in such a way that printf(3) format strings could effectively be specified the low-privilege code. = New features
* sftp-server(8): add a new limitsAATTopenssh.com protocol extension that allows a client to discover various server limits, including maximum packet size and maximum read/write length.
* sftp(1): use the new limitsAATTopenssh.com extension (when available) to select better transfer lengths in the client.
* sshd(8): Add ModuliFile keyword to sshd_config to specify the location of the \"moduli\" file containing the groups for DH-GEX.
* unit tests: Add a TEST_SSH_ELAPSED_TIMES environment variable to enable printing of the elapsed time in seconds of each test. = Bugfixes
* ssh_config(5), sshd_config(5): sync CASignatureAlgorithms lists in manual pages with the current default. GHPR174
* ssh(1): ensure that pkcs11_del_provider() is called before exit. GHPR234
* ssh(1), sshd(8): fix problems in string->argv conversion. Multiple backslashes were not being dequoted correctly and quoted space in the middle of a string was being incorrectly split. GHPR223
* ssh(1): return non-zero exit status when killed by signal; bz#3281
* sftp-server(8): increase maximum SSH2_FXP_READ to match the maximum packet size. Also handle zero-length reads that are not explicitly banned by the spec.- Additional changes from 8.5p1 release: = Security
* ssh-agent(1): fixed a double-free memory corruption that was introduced in OpenSSH 8.2 . We treat all such memory faults as potentially exploitable. This bug could be reached by an attacker with access to the agent socket. = Potentially-incompatible changes
* ssh(1), sshd(8): this release changes the first-preference signature algorithm from ECDSA to ED25519.
* ssh(1), sshd(8): set the TOS/DSCP specified in the configuration for interactive use prior to TCP connect. The connection phase of the SSH session is time-sensitive and often explicitly interactive. The ultimate interactive/bulk TOS/DSCP will be set after authentication completes.
* ssh(1), sshd(8): remove the pre-standardization cipher rijndael-cbcAATTlysator.liu.se. It is an alias for aes256-cbc before it was standardized in RFC4253 (2006), has been deprecated and disabled by default since OpenSSH 7.2 (2016) and was only briefly documented in ssh.1 in 2001.
* ssh(1), sshd(8): update/replace the experimental post-quantum hybrid key exchange method based on Streamlined NTRU Prime coupled with X25519. The previous sntrup4591761x25519-sha512AATTtinyssh.org method is replaced with sntrup761x25519-sha512AATTopenssh.com.
* ssh(1): disable CheckHostIP by default. It provides insignificant benefits while making key rotation significantly more difficult, especially for hosts behind IP-based load-balancers. = New features
* ssh(1): this release enables UpdateHostkeys by default subject to some conservative preconditions: - The key was matched in the UserKnownHostsFile (and not in the GlobalKnownHostsFile). - The same key does not exist under another name. - A certificate host key is not in use. - known_hosts contains no matching wildcard hostname pattern. - VerifyHostKeyDNS is not enabled. - The default UserKnownHostsFile is in use.
* ssh(1), sshd(8): add a new LogVerbose configuration directive for that allows forcing maximum debug logging by file/function/line pattern-lists.
* ssh(1): when prompting the user to accept a new hostkey, display any other host names/addresses already associated with the key.
* ssh(1): allow UserKnownHostsFile=none to indicate that no known_hosts file should be used to identify host keys.
* ssh(1): add a ssh_config KnownHostsCommand option that allows the client to obtain known_hosts data from a command in addition to the usual files.
* ssh(1): add a ssh_config PermitRemoteOpen option that allows the client to restrict the destination when RemoteForward is used with SOCKS.
* ssh(1): for FIDO keys, if a signature operation fails with a \"incorrect PIN\" reason and no PIN was initially requested from the user, then request a PIN and retry the operation. This supports some biometric devices that fall back to requiring PIN when reading of the biometric failed, and devices that require PINs for all hosted credentials.
* sshd(8): implement client address-based rate-limiting via new sshd_config(5) PerSourceMaxStartups and PerSourceNetBlockSize directives that provide more fine-grained control on a per-origin address basis than the global MaxStartups limit. = Bugfixes
* ssh(1): Prefix keyboard interactive prompts with \"(userAATThost)\" to make it easier to determine which connection they are associated with in cases like scp -3, ProxyJump, etc. bz#3224
* sshd(8): fix sshd_config SetEnv directives located inside Match blocks. GHPR201
* ssh(1): when requesting a FIDO token touch on stderr, inform the user once the touch has been recorded.
* ssh(1): prevent integer overflow when ridiculously large ConnectTimeout values are specified, capping the effective value (for most platforms) at 24 days. bz#3229
* ssh(1): consider the ECDSA key subtype when ordering host key algorithms in the client.
* ssh(1), sshd(8): rename the PubkeyAcceptedKeyTypes keyword to PubkeyAcceptedAlgorithms. The previous name incorrectly suggested that it control allowed key algorithms, when this option actually specifies the signature algorithms that are accepted. The previous name remains available as an alias. bz#3253
* ssh(1), sshd(8): similarly, rename HostbasedKeyTypes (ssh) and HostbasedAcceptedKeyTypes (sshd) to HostbasedAcceptedAlgorithms.
* sftp-server(8): add missing lsetstatAATTopenssh.com documentation and advertisement in the server\'s SSH2_FXP_VERSION hello packet.
* ssh(1), sshd(8): more strictly enforce KEX state-machine by banning packet types once they are received. Fixes memleak caused by duplicate SSH2_MSG_KEX_DH_GEX_REQUEST (oss-fuzz #30078).
* sftp(1): allow the full range of UIDs/GIDs for chown/chgrp on 32bit platforms instead of being limited by LONG_MAX. bz#3206
* Minor man page fixes (capitalization, commas, etc.) bz#3223
* sftp(1): when doing an sftp recursive upload or download of a read-only directory, ensure that the directory is created with write and execute permissions in the interim so that the transfer can actually complete, then set the directory permission as the final step. bz#3222
* ssh-keygen(1): document the -Z, check the validity of its argument earlier and provide a better error message if it\'s not correct. bz#2879
* ssh(1): ignore comments at the end of config lines in ssh_config, similar to what we already do for sshd_config. bz#2320
* sshd_config(5): mention that DisableForwarding is valid in a sshd_config Match block. bz3239
* sftp(1): fix incorrect sorting of \"ls -ltr\" under some circumstances. bz3248.
* ssh(1), sshd(8): fix potential integer truncation of (unlikely) timeout values. bz#3250
* ssh(1): make hostbased authentication send the signature algorithm in its SSH2_MSG_USERAUTH_REQUEST packets instead of the key type. This make HostbasedAcceptedAlgorithms do what it is supposed to - filter on signature algorithm and not key type.- Rebased patches:

* ssh(1), ssh-keygen(1): support for FIDO keys that require a PIN for each use. These keys may be generated using ssh-keygen using a new \"verify-required\" option. When a PIN-required key is used, the user will be prompted for a PIN to complete the signature operation. New Features - -----------
* sshd(8): authorized_keys now supports a new \"verify-required\" option to require FIDO signatures assert that the token verified that the user was present before making the signature. The FIDO protocol supports multiple methods for user-verification, but currently OpenSSH only supports PIN verification.
* sshd(8), ssh-keygen(1): add support for verifying FIDO webauthn signatures. Webauthn is a standard for using FIDO keys in web browsers. These signatures are a slightly different format to plain FIDO signatures and thus require explicit support.
* ssh(1): allow some keywords to expand shell-style ${ENV} environment variables. The supported keywords are CertificateFile, ControlPath, IdentityAgent and IdentityFile, plus LocalForward and RemoteForward when used for Unix domain socket paths. bz#3140
* ssh(1), ssh-agent(1): allow some additional control over the use of ssh-askpass via a new $SSH_ASKPASS_REQUIRE environment variable, including forcibly enabling and disabling its use. bz#69
* ssh(1): allow ssh_config(5)\'s AddKeysToAgent keyword accept a time limit for keys in addition to its current flag options. Time- limited keys will automatically be removed from ssh-agent after their expiry time has passed.
* scp(1), sftp(1): allow the -A flag to explicitly enable agent forwarding in scp and sftp. The default remains to not forward an agent, even when ssh_config enables it.
* ssh(1): add a \'%k\' TOKEN that expands to the effective HostKey of the destination. This allows, e.g., keeping host keys in individual files using \"UserKnownHostsFile ~/.ssh/known_hosts.d/%k\". bz#1654
* ssh(1): add %-TOKEN, environment variable and tilde expansion to the UserKnownHostsFile directive, allowing the path to be completed by the configuration (e.g. bz#1654)
* ssh-keygen(1): allow \"ssh-add -d -\" to read keys to be deleted from stdin. bz#3180
* sshd(8): improve logging for MaxStartups connection throttling. sshd will now log when it starts and stops throttling and periodically while in this state. bz#3055 Bugfixes - -------
* ssh(1), ssh-keygen(1): better support for multiple attached FIDO tokens. In cases where OpenSSH cannot unambiguously determine which token to direct a request to, the user is now required to select a token by touching it. In cases of operations that require a PIN to be verified, this avoids sending the wrong PIN to the wrong token and incrementing the token\'s PIN failure counter (tokens effectively erase their keys after too many PIN failures).
* sshd(8): fix Include before Match in sshd_config; bz#3122
* ssh(1): close stdin/out/error when forking after authentication completes (\"ssh -f ...\") bz#3137
* ssh(1), sshd(8): limit the amount of channel input data buffered, avoiding peers that advertise large windows but are slow to read from causing high memory consumption.
* ssh-agent(1): handle multiple requests sent in a single write() to the agent.
* sshd(8): allow sshd_config longer than 256k
* sshd(8): avoid spurious \"Unable to load host key\" message when sshd load a private key but no public counterpart
* ssh(1): prefer the default hostkey algorithm list whenever we have a hostkey that matches its best-preference algorithm.
* sshd(1): when ordering the hostkey algorithms to request from a server, prefer certificate types if the known_hosts files contain a key marked as a AATTcert-authority; bz#3157
* ssh(1): perform host key fingerprint comparisons for the \"Are you sure you want to continue connecting (yes/no/[fingerprint])?\" prompt with case sensitivity.
* sshd(8): ensure that address/masklen mismatches in sshd_config yield fatal errors at daemon start time rather than later when they are evaluated.
* ssh-keygen(1): ensure that certificate extensions are lexically sorted. Previously if the user specified a custom extension then the everything would be in order except the custom ones. bz#3198
* ssh(1): also compare username when checking for JumpHost loops. bz#3057
* ssh-keygen(1): preserve group/world read permission on known_hosts files across runs of \"ssh-keygen -Rf /path\". The old behaviour was to remove all rights for group/other. bz#3146
* ssh-keygen(1): Mention the [-a rounds] flag in the ssh-keygen manual page and usage().
* sshd(8): explicitly construct path to ~/.ssh/rc rather than relying on it being relative to the current directory, so that it can still be found if the shell startup changes its directory. bz#3185
* sshd(8): when redirecting sshd\'s log output to a file, undo this redirection after the session child process is forked(). Fixes missing log messages when using this feature under some circumstances.
* sshd(8): start ClientAliveInterval bookkeeping before first pass through select() loop; fixed theoretical case where busy sshd may ignore timeouts from client.
* ssh(1): only reset the ServerAliveInterval check when we receive traffic from the server and ignore traffic from a port forwarding client, preventing a client from keeping a connection alive when it should be terminated. bz#2265
* ssh-keygen(1): avoid spurious error message when ssh-keygen creates files outside ~/.ssh
* sftp-client(1): fix off-by-one error that caused sftp downloads to make one more concurrent request that desired. This prevented using sftp(1) in unpipelined request/response mode, which is useful when debugging. bz#3054
* ssh(1), sshd(8): handle EINTR in waitfd() and timeout_connect() helpers. bz#3071
* ssh(1), ssh-keygen(1): defer creation of ~/.ssh until we attempt to write to it so we don\'t leave an empty .ssh directory when it\'s not needed. bz#3156
* ssh(1), sshd(8): fix multiplier when parsing time specifications when handling seconds after other units. bz#3171
* Fri Jan 08 2021 Hans Petter Jansson - Update openssh-8.1p1-audit.patch (bsc#1180501). This fixes occasional crashes on connection termination caused by accessing freed memory.
* Fri Nov 27 2020 Thorsten Kukuk - Support /usr/etc/pam.d
* Wed Nov 11 2020 Hans Petter Jansson - Fix build breakage caused by missing security key objects: + Modify openssh-7.7p1-cavstest-ctr.patch. + Modify openssh-7.7p1-cavstest-kdf.patch. + Add openssh-link-with-sk.patch.
* Wed Nov 11 2020 Hans Petter Jansson - Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939). This ensures only approved DH parameters are used in FIPS mode.
* Wed Nov 11 2020 Hans Petter Jansson - Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799). This uses OpenSSL\'s RAND_bytes() directly instead of the internal ChaCha20-based implementation to obtain random bytes for Ed25519 curve computations. This is required for FIPS compliance.
* Thu Oct 08 2020 Hans Petter Jansson - Work around %service_add_post disabling sshd on upgrade with package name change (bsc#1177039).
* Fri Sep 25 2020 Dominique Leuenberger - Fix fillup-template usage: + %post server needs to reference ssh (not sshd), which matches the sysconfig.ssh file name the package ships. + %post client does not need any fillup_ calls, as there is no client-relevant sysconfig file present. The naming of the sysconfig file (ssh instead of sshd) is unfortunate.
* Fri Sep 25 2020 Franck Bui - Use of DISABLE_RESTART_ON_UPDATE is deprecated. Replace it with %service_del_postun_without_restart
* Thu Sep 17 2020 Jan Engelhardt - Move some Requires to the right subpackage.- Avoid \">&\" bashism in %post.- Upgrade some old specfile constructs/macros and drop unnecessary %{?systemd_
*}.- Trim descriptions and straighten out the grammar.
* Thu Sep 10 2020 Hans Petter Jansson - Split openssh package into openssh, openssh-common, openssh-server and openssh-clients. This allows for the ssh clients to be installed without the server component (bsc#1176434).
* Fri Jun 05 2020 Hans Petter Jansson - Version update to 8.3p1: = Potentially-incompatible changes
* sftp(1): reject an argument of \"-1\" in the same way as ssh(1) and scp(1) do instead of accepting and silently ignoring it. = New features
* sshd(8): make IgnoreRhosts a tri-state option: \"yes\" to ignore rhosts/shosts, \"no\" allow rhosts/shosts or (new) \"shosts-only\" to allow .shosts files but not .rhosts.
* sshd(8): allow the IgnoreRhosts directive to appear anywhere in a sshd_config, not just before any Match blocks.
* ssh(1): add %TOKEN percent expansion for the LocalFoward and RemoteForward keywords when used for Unix domain socket forwarding.
* all: allow loading public keys from the unencrypted envelope of a private key file if no corresponding public key file is present.
* ssh(1), sshd(8): prefer to use chacha20 from libcrypto where possible instead of the (slower) portable C implementation included in OpenSSH.
* ssh-keygen(1): add ability to dump the contents of a binary key revocation list via \"ssh-keygen -lQf /path\".- Additional changes from 8.2p1 release: = Potentially-incompatible changes
* ssh(1), sshd(8), ssh-keygen(1): this release removes the \"ssh-rsa\" (RSA/SHA1) algorithm from those accepted for certificate signatures (i.e. the client and server CASignatureAlgorithms option) and will use the rsa-sha2-512 signature algorithm by default when the ssh-keygen(1) CA signs new certificates.
* ssh(1), sshd(8): this release removes diffie-hellman-group14-sha1 from the default key exchange proposal for both the client and server.
* ssh-keygen(1): the command-line options related to the generation and screening of safe prime numbers used by the diffie-hellman-group-exchange-
* key exchange algorithms have changed. Most options have been folded under the -O flag.
* sshd(8): the sshd listener process title visible to ps(1) has changed to include information about the number of connections that are currently attempting authentication and the limits configured by MaxStartups.
* ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F support to provide address-space isolation for token middleware libraries (including the internal one). It needs to be installed in the expected path, typically under /usr/libexec or similar. = New features
* This release adds support for FIDO/U2F hardware authenticators to OpenSSH. U2F/FIDO are open standards for inexpensive two-factor authentication hardware that are widely used for website authentication. In OpenSSH FIDO devices are supported by new public key types \"ecdsa-sk\" and \"ed25519-sk\", along with corresponding certificate types.
* sshd(8): add an Include sshd_config keyword that allows including additional configuration files via glob(3) patterns.
* ssh(1)/sshd(8): make the LE (low effort) DSCP code point available via the IPQoS directive.
* ssh(1): when AddKeysToAgent=yes is set and the key contains no comment, add the key to the agent with the key\'s path as the comment.
* ssh-keygen(1), ssh-agent(1): expose PKCS#11 key labels and X.509 subjects as key comments, rather than simply listing the PKCS#11 provider library path.
* ssh-keygen(1): allow PEM export of DSA and ECDSA keys.
* ssh(1), sshd(8): make zlib compile-time optional, available via the Makefile.inc ZLIB flag on OpenBSD or via the --with-zlib configure option for OpenSSH portable.
* sshd(8): when clients get denied by MaxStartups, send a notification prior to the SSH2 protocol banner according to RFC4253 section 4.2.
* ssh(1), ssh-agent(1): when invoking the $SSH_ASKPASS prompt program, pass a hint to the program to describe the type of desired prompt. The possible values are \"confirm\" (indicating that a yes/no confirmation dialog with no text entry should be shown), \"none\" (to indicate an informational message only), or blank for the original ssh-askpass behaviour of requesting a password/phrase.
* ssh(1): allow forwarding a different agent socket to the path specified by $SSH_AUTH_SOCK, by extending the existing ForwardAgent option to accepting an explicit path or the name of an environment variable in addition to yes/no.
* ssh-keygen(1): add a new signature operations \"find-principals\" to look up the principal associated with a signature from an allowed- signers file.
* sshd(8): expose the number of currently-authenticating connections along with the MaxStartups limit in the process title visible to \"ps\".- Rebased patches:

* openssh-8.1p1-seccomp-clock_gettime64.patch
* Tue Feb 11 2020 Hans Petter Jansson - Add openssh-8.1p1-use-openssl-kdf.patch (jsc#SLE-9443). This performs key derivation using OpenSSL\'s SSHKDF facility, which allows OpenSSH to benefit from the former\'s FIPS certification status.
* Thu Nov 21 2019 Hans Petter Jansson - Make sure ssh-keygen runs if SSHD_AUTO_KEYGEN variable is unset or contains an unrecognized value (bsc#1157176).
* Fri Nov 08 2019 Cristian Rodríguez - Add openssh-8.1p1-seccomp-clock_nanosleep.patch, allow clock_nanosleep glibc master implements multiple functions using that syscall making the privsep sandbox kill the preauth process.
* Thu Oct 17 2019 Hans Petter Jansson - Update openssh-7.7p1-audit.patch to fix crash (bsc#1152730). Fix by Enzo Matsumiya (ematsumiyaAATTsuse.com). This was integrated in a separate code stream merged with the Oct. 10 update; the patch was also rebased and renamed to openssh-8.1p1-audit.patch.
* Mon Oct 14 2019 Hans Petter Jansson - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R).- Added openssh-7.9p1-revert-new-qos-defaults.patch, which reverts an upstream commit that caused compatibility issues with other software (bsc#1136402).
* Mon Oct 14 2019 Hans Petter Jansson - Run \'ssh-keygen -A\' on startup only if SSHD_AUTO_KEYGEN=\"yes\" in /etc/sysconfig/ssh. This is set to \"yes\" by default, but can be changed by the system administrator (bsc#1139089).
* Mon Oct 14 2019 Hans Petter Jansson - Add openssh-7.9p1-keygen-preserve-perms.patch (bsc#1150574). This attempts to preserve the permissions of any existing known_hosts file when modified by ssh-keygen (for instance, with -R).
* Thu Oct 10 2019 Hans Petter Jansson - Version update to 8.1p1:
* ssh-keygen(1): when acting as a CA and signing certificates with an RSA key, default to using the rsa-sha2-512 signature algorithm. Certificates signed by RSA keys will therefore be incompatible with OpenSSH versions prior to 7.2 unless the default is overridden (using \"ssh-keygen -t ssh-rsa -s ...\").
* ssh(1): Allow %n to be expanded in ProxyCommand strings
* ssh(1), sshd(8): Allow prepending a list of algorithms to the default set by starting the list with the \'^\' character, E.g. \"HostKeyAlgorithms ^ssh-ed25519\"
* ssh-keygen(1): add an experimental lightweight signature and verification ability. Signatures may be made using regular ssh keys held on disk or stored in a ssh-agent and verified against an authorized_keys-like list of allowed keys. Signatures embed a namespace that prevents confusion and attacks between different usage domains (e.g. files vs email).
* ssh-keygen(1): print key comment when extracting public key from a private key.
* ssh-keygen(1): accept the verbose flag when searching for host keys in known hosts (i.e. \"ssh-keygen -vF host\") to print the matching host\'s random-art signature too.
* All: support PKCS8 as an optional format for storage of private keys to disk. The OpenSSH native key format remains the default, but PKCS8 is a superior format to PEM if interoperability with non-OpenSSH software is required, as it may use a less insecure key derivation function than PEM\'s.- Additional changes from 8.0p1 release:
* scp(1): Add \"-T\" flag to disable client-side filtering of server file list.
* sshd(8): Remove support for obsolete \"host/port\" syntax.
* ssh(1), ssh-agent(1), ssh-add(1): Add support for ECDSA keys in PKCS#11 tokens.
* ssh(1), sshd(8): Add experimental quantum-computing resistant key exchange method, based on a combination of Streamlined NTRU Prime 4591^761 and X25519.
* ssh-keygen(1): Increase the default RSA key size to 3072 bits, following NIST Special Publication 800-57\'s guidance for a 128-bit equivalent symmetric security level.
* ssh(1): Allow \"PKCS11Provider=none\" to override later instances of the PKCS11Provider directive in ssh_config,
* sshd(8): Add a log message for situations where a connection is dropped for attempting to run a command but a sshd_config ForceCommand=internal-sftp restriction is in effect.
* ssh(1): When prompting whether to record a new host key, accept the key fingerprint as a synonym for \"yes\". This allows the user to paste a fingerprint obtained out of band at the prompt and have the client do the comparison for you.
* ssh-keygen(1): When signing multiple certificates on a single command-line invocation, allow automatically incrementing the certificate serial number.
* scp(1), sftp(1): Accept -J option as an alias to ProxyJump on the scp and sftp command-lines.
* ssh-agent(1), ssh-pkcs11-helper(8), ssh-add(1): Accept \"-v\" command-line flags to increase the verbosity of output; pass verbose flags though to subprocesses, such as ssh-pkcs11-helper started from ssh-agent.
* ssh-add(1): Add a \"-T\" option to allowing testing whether keys in an agent are usable by performing a signature and a verification.
* sftp-server(8): Add a \"lsetstatAATTopenssh.com\" protocol extension that replicates the functionality of the existing SSH2_FXP_SETSTAT operation but does not follow symlinks.
* sftp(1): Add \"-h\" flag to chown/chgrp/chmod commands to request they do not follow symlinks.
* sshd(8): Expose $SSH_CONNECTION in the PAM environment. This makes the connection 4-tuple available to PAM modules that wish to use it in decision-making.
* sshd(8): Add a ssh_config \"Match final\" predicate Matches in same pass as \"Match canonical\" but doesn\'t require hostname canonicalisation be enabled.
* sftp(1): Support a prefix of \'AATT\' to suppress echo of sftp batch commands.
* ssh-keygen(1): When printing certificate contents using \"ssh-keygen -Lf /path/certificate\", include the algorithm that the CA used to sign the cert.- Rebased patches:

* Mon Oct 22 2018 Pedro Monreal Gonzalez - Version update to 7.9p1
* ssh(1), sshd(8): the setting of the new CASignatureAlgorithms option (see below) bans the use of DSA keys as certificate authorities.
* sshd(8): the authentication success/failure log message has changed format slightly. It now includes the certificate fingerprint (previously it included only key ID and CA key fingerprint).
* ssh(1), sshd(8): allow most port numbers to be specified using service names from getservbyname(3) (typically /etc/services).
* sshd(8): support signalling sessions via the SSH protocol. A limited subset of signals is supported and only for login or command sessions (i.e. not subsystems) that were not subject to a forced command via authorized_keys or sshd_config. bz#1424
* ssh(1): support \"ssh -Q sig\" to list supported signature options. Also \"ssh -Q help\" to show the full set of supported queries.
* ssh(1), sshd(8): add a CASignatureAlgorithms option for the client and server configs to allow control over which signature formats are allowed for CAs to sign certificates. For example, this allows banning CAs that sign certificates using the RSA-SHA1 signature algorithm.
* sshd(8), ssh-keygen(1): allow key revocation lists (KRLs) to revoke keys specified by SHA256 hash.
* ssh-keygen(1): allow creation of key revocation lists directly from base64-encoded SHA256 fingerprints. This supports revoking keys using only the information contained in sshd(8) authentication log messages.- Removed obsolete configuration option --with-tcp-wrappers, and - -with-opensc for s390 and s390x.- Removed patch merged upstream

* Tue Sep 18 2018 schwabAATTsuse.de- seccomp_filter sandbox is not supported on ppc
* Mon Aug 27 2018 tchvatalAATTsuse.com- Depend explicitly on zlib-devel, previously pulled in by openssl
* Mon Jun 25 2018 astiegerAATTsuse.com- BuildRequire pkgconfig(krb5) instead of krb5-mini-devel to ensure zypper si can pick a resolvable provider. Build cycle remains solved via project config pulling in -mini. (bsc#1099044)
* Mon May 21 2018 pcernyAATTsuse.com- Upgrade to 7.7p1 (bsc#1094068) Most important changes (more details below):
* Drop compatibility support for pre-2001 SSH implementations
* sshd(1) does not load DSA keys by default Distilled upstream log: - --- Potentially-incompatible changes
* ssh(1)/sshd(8): Drop compatibility support for some very old SSH implementations, including ssh.com <=2.
* and OpenSSH <= 3.
*. These versions were all released in or before 2001 and predate the final SSH RFCs. The support in question isn\'t necessary for RFC-compliant SSH implementations. - --- New Features
* experimental support for PQC XMSS keys (Extended Hash-Based Signatures), not compiled in by default.
* sshd(8): Add a \"rdomain\" criteria for the sshd_config Match keyword to allow conditional configuration that depends on which routing domain a connection was received on (currently supported on OpenBSD and Linux).
* sshd_config(5): Add an optional rdomain qualifier to the ListenAddress directive to allow listening on different routing domains. This is supported only on OpenBSD and Linux at present.
* sshd_config(5): Add RDomain directive to allow the authenticated session to be placed in an explicit routing domain. This is only supported on OpenBSD at present.
* sshd(8): Add \"expiry-time\" option for authorized_keys files to allow for expiring keys.
* ssh(1): Add a BindInterface option to allow binding the outgoing connection to an interface\'s address (basically a more usable BindAddress)
* ssh(1): Expose device allocated for tun/tap forwarding via a new %T expansion for LocalCommand. This allows LocalCommand to be %used to prepare the interface.
* sshd(8): Expose the device allocated for tun/tap forwarding via a new SSH_TUNNEL environment variable. This allows automatic setup of the interface and surrounding network configuration automatically on the server.
* ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g. ssh://userAATThost or sftp://userAATThost/path. Additional connection parameters that use deporecated MD5 are not implemented.
* ssh-keygen(1): Allow certificate validity intervals that specify only a start or stop time (instead of both or neither).
* sftp(1): Allow \"cd\" and \"lcd\" commands with no explicit path argument. lcd will change to the local user\'s home directory as usual. cd will change to the starting directory for session (because the protocol offers no way to obtain the remote user\'s home directory). bz#2760
* sshd(8): When doing a config test with sshd -T, only require the attributes that are actually used in Match criteria rather than (an incomplete list of) all criteria. - --- Bugfixes
* ssh(1)/sshd(8): More strictly check signature types during key exchange against what was negotiated. Prevents downgrade of RSA signatures made with SHA-256/512 to SHA-1.
* sshd(8): Fix support for client that advertise a protocol version of \"1.99\" (indicating that they are prepared to accept both SSHv1 and SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1 support. bz#2810
* ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when a rsa-sha2-256/512 signature was requested. This condition is possible when an old or non-OpenSSH agent is in use. bz#2799
* ssh-agent(1): Fix regression introduced in 7.6 that caused ssh-agent to fatally exit if presented an invalid signature request message.
* sshd_config(5): Accept yes/no flag options case-insensitively, as has been the case in ssh_config(5) for a long time. bz#2664
* ssh(1): Improve error reporting for failures during connection. Under some circumstances misleading errors were being shown. bz#2814
* ssh-keyscan(1): Add -D option to allow printing of results directly in SSHFP format. bz#2821
* regress tests: fix PuTTY interop test broken in last release\'s SSHv1 removal. bz#2823
* ssh(1): Compatibility fix for some servers that erroneously drop the connection when the IUTF8 (RFC8160) option is sent.
* scp(1): Disable RemoteCommand and RequestTTY in the ssh session started by scp (sftp was already doing this.)
* ssh-keygen(1): Refuse to create a certificate with an unusable number of principals.
* ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the public key during key generation. Previously it would silently ignore errors writing the comment and terminating newline.
* ssh(1): Do not modify hostname arguments that are addresses by automatically forcing them to lower-case. Instead canonicalise them to resolve ambiguities (e.g. ::0001 => ::1) before they are matched against known_hosts. bz#2763
* ssh(1): Don\'t accept junk after \"yes\" or \"no\" responses to hostkey prompts. bz#2803
* sftp(1): Have sftp print a warning about shell cleanliness when decoding the first packet fails, which is usually caused by shells polluting stdout of non-interactive startups. bz#2800
* ssh(1)/sshd(8): Switch timers in packet code from using wall-clock time to monotonic time, allowing the packet layer to better function over a clock step and avoiding possible integer overflows during steps.
* Numerous manual page fixes and improvements.
* Wed May 02 2018 dimstarAATTopensuse.org- Use TIRPC on suse_version >= 1500: sunrpc is deprecated and should be replaced by TIRPC.
* Mon Apr 30 2018 pcernyAATTsuse.com- additional rebased patches (bsc#1080779)
* auditing support
* LDAP integration
* various distribution tweaks from SLE12 (X forwarding over IPv6, sftp forced permissions and verbose batch mode)
* Wed Apr 04 2018 kukukAATTsuse.de- Use %license instead of %doc [bsc#1082318]
* Mon Feb 12 2018 pcernyAATTsuse.com- add OpenSSL 1.0 to 1.1 shim to remove dependency on old OpenSSL (update tracker: bsc#1080779)
* Wed Jan 31 2018 pcernyAATTsuse.com- Add missing crypto hardware enablement patches for IBM mainframes (FATE#323902)
* Wed Jan 24 2018 pcernyAATTsuse.com- add missing part of systemd integration (unit type)
* Tue Jan 16 2018 dimstarAATTopensuse.org- BuildRequire pkgconfig(libsystemd) instead of systemd-devel: allow the scheduler to pick systemd-mini flavors to get build going.
* Fri Jan 12 2018 pcernyAATTsuse.com- Replace forgotten references to /var/adm/fillup-templates with new %_fillupdir macro (boo#1069468)- tighten configuration access rights
* Thu Jan 11 2018 pcernyAATTsuse.com- Update to vanilla 7.6p1 Most important changes (more details below):
* complete removal of the ancient SSHv1 protocol
* sshd(8) cannot run without privilege separation
* removal of suport for arcfourm blowfish and CAST ciphers and RIPE-MD160 HMAC
* refuse RSA keys shorter than 1024 bits Distilled upstream log:- OpenSSH 7.3 - --- Security
* sshd(8): Mitigate a potential denial-of-service attack against the system\'s crypt(3) function via sshd(8). An attacker could send very long passwords that would cause excessive CPU use in crypt(3). sshd(8) now refuses to accept password authentication requests of length greater than 1024 characters. Independently reported by Tomas Kuthan (Oracle), Andres Rojas and Javier Nieto.
* sshd(8): Mitigate timing differences in password authentication that could be used to discern valid from invalid account names when long passwords were sent and particular password hashing algorithms are in use on the server. CVE-2016-6210, reported by EddieEzra.Harari at verint.com
* ssh(1), sshd(8): Fix observable timing weakness in the CBC padding oracle countermeasures. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht. Note that CBC ciphers are disabled by default and only included for legacy compatibility.
* ssh(1), sshd(8): Improve operation ordering of MAC verification for Encrypt-then-MAC (EtM) mode transport MAC algorithms to verify the MAC before decrypting any ciphertext. This removes the possibility of timing differences leaking facts about the plaintext, though no such leakage has been observed. Reported by Jean Paul Degabriele, Kenny Paterson, Torben Hansen and Martin Albrecht.
* sshd(8): (portable only) Ignore PAM environment vars when UseLogin=yes. If PAM is configured to read user-specified environment variables and UseLogin=yes in sshd_config, then a hostile local user may attack /bin/login via LD_PRELOAD or similar environment variables set via PAM. CVE-2015-8325, found by Shayan Sadigh. - --- New Features
* ssh(1): Add a ProxyJump option and corresponding -J command-line flag to allow simplified indirection through a one or more SSH bastions or \"jump hosts\".
* ssh(1): Add an IdentityAgent option to allow specifying specific agent sockets instead of accepting one from the environment.
* ssh(1): Allow ExitOnForwardFailure and ClearAllForwardings to be optionally overridden when using ssh -W. bz#2577
* ssh(1), sshd(8): Implement support for the IUTF8 terminal mode as per draft-sgtatham-secsh-iutf8-00.
* ssh(1), sshd(8): Add support for additional fixed Diffie-Hellman 2K, 4K and 8K groups from draft-ietf-curdle-ssh-kex-sha2-03.
* ssh-keygen(1), ssh(1), sshd(8): support SHA256 and SHA512 RSA signatures in certificates;
* ssh(1): Add an Include directive for ssh_config(5) files.
* ssh(1): Permit UTF-8 characters in pre-authentication banners sent from the server. bz#2058 - --- Bugfixes
* ssh(1), sshd(8): Reduce the syslog level of some relatively common protocol events from LOG_CRIT. bz#2585
* sshd(8): Refuse AuthenticationMethods=\"\" in configurations and accept AuthenticationMethods=any for the default behaviour of not requiring multiple authentication. bz#2398
* sshd(8): Remove obsolete and misleading \"POSSIBLE BREAK-IN ATTEMPT!\" message when forward and reverse DNS don\'t match. bz#2585
* ssh(1): Close ControlPersist background process stderr except in debug mode or when logging to syslog. bz#1988
* misc: Make PROTOCOL description for direct-streamlocalAATTopenssh.com channel open messages match deployed code. bz#2529
* ssh(1): Deduplicate LocalForward and RemoteForward entries to fix failures when both ExitOnForwardFailure and hostname canonicalisation are enabled. bz#2562
* sshd(8): Remove fallback from moduli to obsolete \"primes\" file that was deprecated in 2001. bz#2559.
* sshd_config(5): Correct description of UseDNS: it affects ssh hostname processing for authorized_keys, not known_hosts; bz#2554
* ssh(1): Fix authentication using lone certificate keys in an agent without corresponding private keys on the filesystem. bz#2550
* sshd(8): Send ClientAliveInterval pings when a time-based RekeyLimit is set; previously keepalive packets were not being sent. bz#2252 - --- Portability
* ssh(1), sshd(8): Fix compilation by automatically disabling ciphers not supported by OpenSSL. bz#2466
* misc: Fix compilation failures on some versions of AIX\'s compiler related to the definition of the VA_COPY macro. bz#2589
* sshd(8): Whitelist more architectures to enable the seccomp-bpf sandbox. bz#2590
* ssh-agent(1), sftp-server(8): Disable process tracing on Solaris using setpflags(__PROC_PROTECT, ...). bz#2584
* sshd(8): On Solaris, don\'t call Solaris setproject() with UsePAM=yes it\'s PAM\'s responsibility. bz#2425- OpenSSH 7.4 - --- Potentially-incompatible changes
* ssh(1): Remove 3des-cbc from the client\'s default proposal. 64-bit block ciphers are not safe in 2016 and we don\'t want to wait until attacks like SWEET32 are extended to SSH. As 3des-cbc was the only mandatory cipher in the SSH RFCs, this may cause problems connecting to older devices using the default configuration, but it\'s highly likely that such devices already need explicit configuration for key exchange and hostkey algorithms already anyway.
* sshd(8): Remove support for pre-authentication compression. Doing compression early in the protocol probably seemed reasonable in the 1990s, but today it\'s clearly a bad idea in terms of both cryptography (cf. multiple compression oracle attacks in TLS) and attack surface. Pre-auth compression support has been disabled by default for >10 years. Support remains in the client.
* ssh-agent will refuse to load PKCS#11 modules outside a whitelist of trusted paths by default. The path whitelist may be specified at run-time.
* sshd(8): When a forced-command appears in both a certificate and an authorized keys/principals command= restriction, sshd will now refuse to accept the certificate unless they are identical. The previous (documented) behaviour of having the certificate forced-command override the other could be a bit confusing and error-prone.
* sshd(8): Remove the UseLogin configuration directive and support for having /bin/login manage login sessions. - --- Security
* ssh-agent(1): Will now refuse to load PKCS#11 modules from paths outside a trusted whitelist (run-time configurable). Requests to load modules could be passed via agent forwarding and an attacker could attempt to load a hostile PKCS#11 module across the forwarded agent channel: PKCS#11 modules are shared libraries, so this would result in code execution on the system running the ssh-agent if the attacker has control of the forwarded agent-socket (on the host running the sshd server) and the ability to write to the filesystem of the host running ssh-agent (usually the host running the ssh client). Reported by Jann Horn of Project Zero.
* sshd(8): When privilege separation is disabled, forwarded Unix- domain sockets would be created by sshd(8) with the privileges of \'root\' instead of the authenticated user. This release refuses Unix-domain socket forwarding when privilege separation is disabled (Privilege separation has been enabled by default for 14 years). Reported by Jann Horn of Project Zero.
* sshd(8): Avoid theoretical leak of host private key material to privilege-separated child processes via realloc() when reading keys. No such leak was observed in practice for normal-sized keys, nor does a leak to the child processes directly expose key material to unprivileged users. Reported by Jann Horn of Project Zero.
* sshd(8): The shared memory manager used by pre-authentication compression support had a bounds checks that could be elided by some optimising compilers. Additionally, this memory manager was incorrectly accessible when pre-authentication compression was disabled. This could potentially allow attacks against the privileged monitor process from the sandboxed privilege-separation process (a compromise of the latter would be required first). This release removes support for pre-authentication compression from sshd(8). Reported by Guido Vranken using the Stack unstable optimisation identification tool (http://css.csail.mit.edu/stack/)
* sshd(8): Fix denial-of-service condition where an attacker who sends multiple KEXINIT messages may consume up to 128MB per connection. Reported by Shi Lei of Gear Team, Qihoo 360.
* sshd(8): Validate address ranges for AllowUser and DenyUsers directives at configuration load time and refuse to accept invalid ones. It was previously possible to specify invalid CIDR address ranges (e.g. userAATT127.1.2.3/55) and these would always match, possibly resulting in granting access where it was not intended. Reported by Laurence Parry. - --- New Features
* ssh(1): Add a proxy multiplexing mode to ssh(1) inspired by the version in PuTTY by Simon Tatham. This allows a multiplexing client to communicate with the master process using a subset of the SSH packet and channels protocol over a Unix-domain socket, with the main process acting as a proxy that translates channel IDs, etc. This allows multiplexing mode to run on systems that lack file- descriptor passing (used by current multiplexing code) and potentially, in conjunction with Unix-domain socket forwarding, with the client and multiplexing master process on different machines. Multiplexing proxy mode may be invoked using \"ssh -O proxy ...\"
* sshd(8): Add a sshd_config DisableForwarding option that disables X11, agent, TCP, tunnel and Unix domain socket forwarding, as well as anything else we might implement in the future. Like the \'restrict\' authorized_keys flag, this is intended to be a simple and future-proof way of restricting an account.
* sshd(8), ssh(1): Support the \"curve25519-sha256\" key exchange method. This is identical to the currently-supported method named \"curve25519-sha256AATTlibssh.org\".
* sshd(8): Improve handling of SIGHUP by checking to see if sshd is already daemonised at startup and skipping the call to daemon(3) if it is. This ensures that a SIGHUP restart of sshd(8) will retain the same process-ID as the initial execution. sshd(8) will also now unlink the PidFile prior to SIGHUP restart and re-create it after a successful restart, rather than leaving a stale file in the case of a configuration error. bz#2641
* sshd(8): Allow ClientAliveInterval and ClientAliveCountMax directives to appear in sshd_config Match blocks.
* sshd(8): Add %-escapes to AuthorizedPrincipalsCommand to match those supported by AuthorizedKeysCommand (key, key type, fingerprint, etc.) and a few more to provide access to the contents of the certificate being offered.
* Added regression tests for string matching, address matching and string sanitisation functions.
* Improved the key exchange fuzzer harness. - --- Bugfixes
* ssh(1): Allow IdentityFile to successfully load and use certificates that have no corresponding bare public key. bz#2617 certificate id_rsa-cert.pub (and no id_rsa.pub).
* ssh(1): Fix public key authentication when multiple authentication is in use and publickey is not just the first method attempted. bz#2642
* regress: Allow the PuTTY interop tests to run unattended. bz#2639
* ssh-agent(1), ssh(1): improve reporting when attempting to load keys from PKCS#11 tokens with fewer useless log messages and more detail in debug messages. bz#2610
* ssh(1): When tearing down ControlMaster connections, don\'t pollute stderr when LogLevel=quiet.
* sftp(1): On ^Z wait for underlying ssh(1) to suspend before suspending sftp(1) to ensure that ssh(1) restores the terminal mode correctly if suspended during a password prompt.
* ssh(1): Avoid busy-wait when ssh(1) is suspended during a password prompt.
* ssh(1), sshd(8): Correctly report errors during sending of ext- info messages.
* sshd(8): fix NULL-deref crash if sshd(8) received an out-of- sequence NEWKEYS message.
* sshd(8): Correct list of supported signature algorithms sent in the server-sig-algs extension. bz#2547
* sshd(8): Fix sending ext_info message if privsep is disabled.
* sshd(8): more strictly enforce the expected ordering of privilege separation monitor calls used for authentication and allow them only when their respective authentication methods are enabled in the configuration
* sshd(8): Fix uninitialised optlen in getsockopt() call; harmless on Unix/BSD but potentially crashy on Cygwin.
* Fix false positive reports caused by explicit_bzero(3) not being recognised as a memory initialiser when compiled with - fsanitize-memory.
* sshd_config(5): Use 2001:db8::/32, the official IPv6 subnet for configuration examples. - --- Portability
* On environments configured with Turkish locales, fall back to the C/POSIX locale to avoid errors in configuration parsing caused by that locale\'s unique handling of the letters \'i\' and \'I\'. bz#2643
* sftp-server(8), ssh-agent(1): Deny ptrace on OS X using ptrace(PT_DENY_ATTACH, ..)
* ssh(1), sshd(8): Unbreak AES-CTR ciphers on old (~0.9.8) OpenSSL.
* Fix compilation for libcrypto compiled without RIPEMD160 support.
* contrib: Add a gnome-ssh-askpass3 with GTK+3 support. bz#2640
* sshd(8): Improve PRNG reseeding across privilege separation and force libcrypto to obtain a high-quality seed before chroot or sandboxing.
* All: Explicitly test for broken strnvis. NetBSD added an strnvis and unfortunately made it incompatible with the existing one in OpenBSD and Linux\'s libbsd (the former having existed for over ten years). Try to detect this mess, and assume the only safe option if we\'re cross compiling.- OpenSSH 7.5 - --- Potentially-incompatible changes
* This release deprecates the sshd_config UsePrivilegeSeparation option, thereby making privilege separation mandatory. Privilege separation has been on by default for almost 15 years and sandboxing has been on by default for almost the last five.
* The format of several log messages emitted by the packet code has changed to include additional information about the user and their authentication state. Software that monitors ssh/sshd logs may need to account for these changes. For example: Connection closed by user x 1.1.1.1 port 1234 [preauth] Connection closed by authenticating user x 10.1.1.1 port 1234 [preauth] Connection closed by invalid user x 1.1.1.1 port 1234 [preauth] Affected messages include connection closure, timeout, remote disconnection, negotiation failure and some other fatal messages generated by the packet code.
* [Portable OpenSSH only] This version removes support for building against OpenSSL versions prior to 1.0.1. OpenSSL stopped supporting versions prior to 1.0.1 over 12 months ago (i.e. they no longer receive fixes for security bugs). - --- Security
* ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed. Note that the OpenSSH client disables CBC ciphers by default, sshd offers them as lowest-preference options and will remove them by default entriely in the next release. Reported by Jean Paul Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of Royal Holloway, University of London.
* sftp-client(1): [portable OpenSSH only] On Cygwin, a client making a recursive file transfer could be maniuplated by a hostile server to perform a path-traversal attack. creating or modifying files outside of the intended target directory. Reported by Jann Horn of Google Project Zero. - --- New Features
* ssh(1), sshd(8): Support \"=-\" syntax to easily remove methods from algorithm lists, e.g. Ciphers=-
*cbc. bz#2671 - --- Bugfixes
* sshd(1): Fix NULL dereference crash when key exchange start messages are sent out of sequence.
* ssh(1), sshd(8): Allow form-feed characters to appear in configuration files.
* sshd(8): Fix regression in OpenSSH 7.4 support for the server-sig-algs extension, where SHA2 RSA signature methods were not being correctly advertised. bz#2680
* ssh(1), ssh-keygen(1): Fix a number of case-sensitivity bugs in known_hosts processing. bz#2591 bz#2685
* ssh(1): Allow ssh to use certificates accompanied by a private key file but no corresponding plain
*.pub public key. bz#2617
* ssh(1): When updating hostkeys using the UpdateHostKeys option, accept RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA keys when only the ssh-rsa-sha2-
* methods were enabled in HostkeyAlgorithms and not the old ssh-rsa method. bz#2650
* ssh(1): Detect and report excessively long configuration file lines. bz#2651
* Merge a number of fixes found by Coverity and reported via Redhat and FreeBSD. Includes fixes for some memory and file descriptor leaks in error paths. bz#2687
* ssh-keyscan(1): Correctly hash hosts with a port number. bz#2692
* ssh(1), sshd(8): When logging long messages to stderr, don\'t truncate \"\\r\
\" if the length of the message exceeds the buffer. bz#2688
* ssh(1): Fully quote [host]:port in generated ProxyJump/-J command- line; avoid confusion over IPv6 addresses and shells that treat square bracket characters specially.
* ssh-keygen(1): Fix corruption of known_hosts when running \"ssh-keygen -H\" on a known_hosts containing already-hashed entries.
* Fix various fallout and sharp edges caused by removing SSH protocol 1 support from the server, including the server banner string being incorrectly terminated with only \
(instead of \\r\
), confusing error messages from ssh-keyscan bz#2583 and a segfault in sshd if protocol v.1 was enabled for the client and sshd_config contained references to legacy keys bz#2686.
* ssh(1), sshd(8): Free fd_set on connection timeout. bz#2683
* sshd(8): Fix Unix domain socket forwarding for root (regression in OpenSSH 7.4).
* sftp(1): Fix division by zero crash in \"df\" output when server returns zero total filesystem blocks/inodes.
* ssh(1), ssh-add(1), ssh-keygen(1), sshd(8): Translate OpenSSL errors encountered during key loading to more meaningful error codes. bz#2522 bz#2523
* ssh-keygen(1): Sanitise escape sequences in key comments sent to printf but preserve valid UTF-8 when the locale supports it; bz#2520
* ssh(1), sshd(8): Return reason for port forwarding failures where feasible rather than always \"administratively prohibited\". bz#2674

* Regression tests: several reliability fixes. bz#2654 bz#2658 bz#2659
* ssh(1): Fix typo in ~C error message for bad port forward cancellation. bz#2672

* sftp-client(1): Fix non-exploitable integer overflow in SSH2_FXP_NAME response handling.
* ssh-agent(1): Fix regression in 7.4 of deleting PKCS#11-hosted keys. It was not possible to delete them except by specifying their full physical path. bz#2682 - --- Portability

* build: Fix compilation problems caused by unconditionally defining _XOPEN_SOURCE in wide character detection.
* sshd(8): Fix sandbox violations for clock_gettime VSDO syscall fallback on some Linux/X32 kernels. bz#2142- OpenSSH 7.6 - --- Potentially-incompatible changes This release includes a number of changes that may affect existing configurations:
* ssh(1): delete SSH protocol version 1 support, associated configuration options and documentation.
* ssh(1)/sshd(8): remove support for the hmac-ripemd160 MAC.
* ssh(1)/sshd(8): remove support for the arcfour, blowfish and CAST ciphers.
* Refuse RSA keys <1024 bits in length and improve reporting for keys that do not meet this requirement.
* ssh(1): do not offer CBC ciphers by default. - --- Security
* sftp-server(8): in read-only mode, sftp-server was incorrectly permitting creation of zero-length files. Reported by Michal Zalewski. - --- New Features
* ssh(1): add RemoteCommand option to specify a command in the ssh config file instead of giving it on the client\'s command line. This allows the configuration file to specify the command that will be executed on the remote host.
* sshd(8): add ExposeAuthInfo option that enables writing details of the authentication methods used (including public keys where applicable) to a file that is exposed via a $SSH_USER_AUTH environment variable in the subsequent session.
* ssh(1): add support for reverse dynamic forwarding. In this mode, ssh will act as a SOCKS4/5 proxy and forward connections to destinations requested by the remote SOCKS client. This mode is requested using extended syntax for the - R and RemoteForward options and, because it is implemented solely at the client, does not require the server be updated to be supported.
* sshd(8): allow LogLevel directive in sshd_config Match blocks; bz#2717
* ssh-keygen(1): allow inclusion of arbitrary string or flag certificate extensions and critical options.
* ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as a CA when signing certificates. bz#2377
* ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit ToS/DSCP value and just use the operating system default.
* ssh-add(1): added -q option to make ssh-add quiet on success.
* ssh(1): expand the StrictHostKeyChecking option with two new settings. The first \"accept-new\" will automatically accept hitherto-unseen keys but will refuse connections for changed or invalid hostkeys. This is a safer subset of the current behaviour of StrictHostKeyChecking=no. The second setting \"off\", is a synonym for the current behaviour of StrictHostKeyChecking=no: accept new host keys, and continue connection for hosts with incorrect hostkeys. A future release will change the meaning of StrictHostKeyChecking=no to the behaviour of \"accept-new\". bz#2400
* ssh(1): add SyslogFacility option to ssh(1) matching the equivalent option in sshd(8). bz#2705 - --- Bugfixes
* ssh(1): use HostKeyAlias if specified instead of hostname for matching host certificate principal names; bz#2728
* sftp(1): implement sorting for globbed ls; bz#2649
* ssh(1): add a userAATThost prefix to client\'s \"Permission denied\" messages, useful in particular when using \"stacked\" connections (e.g. ssh -J) where it\'s not clear which host is denying. bz#2720
* ssh(1): accept unknown EXT_INFO extension values that contain \\0 characters. These are legal, but would previously cause fatal connection errors if received.
* ssh(1)/sshd(8): repair compression statistics printed at connection exit
* sftp(1): print \'?\' instead of incorrect link count (that the protocol doesn\'t provide) for remote listings. bz#2710
* ssh(1): return failure rather than fatal() for more cases during session multiplexing negotiations. Causes the session to fall back to a non-mux connection if they occur. bz#2707
* ssh(1): mention that the server may send debug messages to explain public key authentication problems under some circumstances; bz#2709
* Translate OpenSSL error codes to better report incorrect passphrase errors when loading private keys; bz#2699
* sshd(8): adjust compatibility patterns for WinSCP to correctly identify versions that implement only the legacy DH group exchange scheme. bz#2748
* ssh(1): print the \"Killed by signal 1\" message only at LogLevel verbose so that it is not shown at the default level; prevents it from appearing during ssh -J and equivalent ProxyCommand configs. bz#1906, bz#2744
* ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber existing keys if they exist but are zero length. zero-length keys could previously be made if ssh-keygen failed or was interrupted part way through generating them. bz#2561
* ssh(1): fix pledge(2) violation in the escape sequence \"~&\" used to place the current session in the background.
* ssh-keyscan(1): avoid double-close() on file descriptors; bz#2734
* sshd(8): avoid reliance on shared use of pointers shared between monitor and child sshd processes. bz#2704
* sshd_config(8): document available AuthenticationMethods; bz#2453
* ssh(1): avoid truncation in some login prompts; bz#2768
* sshd(8): Fix various compilations failures, inc bz#2767
* ssh(1): make \"--\" before the hostname terminate argument processing after the hostname too.
* ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting new-style private keys. Fixes problems related to private key handling for no-OpenSSL builds. bz#2754
* ssh(1): warn and do not attempt to use keys when the public and private halves do not match. bz#2737
* sftp(1): don\'t print verbose error message when ssh disconnects from under sftp. bz#2750
* sshd(8): fix keepalive scheduling problem: activity on a forwarded port from preventing the keepalive from being sent; bz#2756
* sshd(8): when started without root privileges, don\'t require the privilege separation user or path to exist. Makes running the regression tests easier without touching the filesystem.
* Make integrity.sh regression tests more robust against timeouts. bz#2658
* ssh(1)/sshd(8): correctness fix for channels implementation: accept channel IDs greater than 0x7FFFFFFF. - --- Portability
* sshd(9): drop two more privileges in the Solaris sandbox: PRIV_DAX_ACCESS and PRIV_SYS_IB_INFO; bz#2723
* sshd(8): expose list of completed authentication methods to PAM via the SSH_AUTH_INFO_0 PAM environment variable. bz#2408
* ssh(1)/sshd(8): fix several problems in the tun/tap forwarding code, mostly to do with host/network byte order confusion. bz#2735
* Add --with-cflags-after and --with-ldflags-after configure flags to allow setting CFLAGS/LDFLAGS after configure has completed. These are useful for setting sanitiser/fuzzing options that may interfere with configure\'s operation.
* sshd(8): avoid Linux seccomp violations on ppc64le over the socketcall syscall.
* Fix use of ldns when using ldns-config; bz#2697
* configure: set cache variables when cross-compiling. The cross- compiling fallback message was saying it assumed the test passed, but it wasn\'t actually set the cache variables and this would cause later tests to fail.
* Add clang libFuzzer harnesses for public key parsing and signature verification.- packaging:
