Sun Apr 17 14:00:00 2016 pcernyAATTsuse.com
- upgrade to 7.2p2 (FATE#319675)
upstream package without any SUSE patches
Distilled upstream log:
- OpenSSH 6.7
Potentially-incompatible changes:
* sshd(8): The default set of ciphers and MACs has been
altered to remove unsafe algorithms. In particular, CBC
ciphers and arcfour
* are disabled by default.
The full set of algorithms remains available if configured
explicitly via the Ciphers and MACs sshd_config options.
* sshd(8): Support for tcpwrappers/libwrap has been removed.
* OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of
connections using the curve25519-sha256AATTlibssh.org KEX
exchange method to fail when connecting with something that
implements the specification correctly. OpenSSH 6.7 disables
this KEX method when speaking to one of the affected
versions.
New Features:
* ssh(1), sshd(8): Add support for Unix domain socket
forwarding. A remote TCP port may be forwarded to a local
Unix domain socket and vice versa or both ends may be a Unix
domain socket.
* ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for
ED25519 key types.
* sftp(1): Allow resumption of interrupted uploads.
* ssh(1): When rekeying, skip file/DNS lookups of the hostkey
if it is the same as the one sent during initial key exchange
* sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind
addresses when GatewayPorts=no; allows client to choose
address family
* sshd(8): Add a sshd_config PermitUserRC option to control
whether ~/.ssh/rc is executed, mirroring the no-user-rc
authorized_keys option
* ssh(1): Add a %C escape sequence for LocalCommand and
ControlPath that expands to a unique identifer based on a
hash of the tuple of (local host, remote user, hostname,
port). Helps avoid exceeding miserly pathname limits for Unix
domain sockets in multiplexing control paths
* sshd(8): Make the \"Too many authentication failures\" message
include the user, source address, port and protocol in a
format similar to the authentication success / failure
messages
Bugfixes:
* sshd(8): Fix remote forwarding with the same listen port but
different listen address.
* ssh(1): Fix inverted test that caused PKCS#11 keys that were
explicitly listed in ssh_config or on the commandline not to
be preferred.
* ssh-keygen(1): Fix bug in KRL generation: multiple
consecutive revoked certificate serial number ranges could be
serialised to an invalid format. Readers of a broken KRL
caused by this bug will fail closed, so no
should-have-been-revoked key will be accepted.
* ssh(1): Reflect stdio-forward (\"ssh -W host:port ...\")
failures in exit status. Previously we were always returning 0
* ssh(1), ssh-keygen(1): Make Ed25519 keys\' title fit properly
in the randomart border
* ssh-agent(1): Only cleanup agent socket in the main agent
process and not in any subprocesses it may have started (e.g.
forked askpass). Fixes agent sockets being zapped when
askpass processes fatal()
* ssh-add(1): Make stdout line-buffered; saves partial output
getting lost when ssh-add fatal()s part-way through (e.g.
when listing keys from an agent that supports key types that
ssh-add doesn\'t)
* ssh-keygen(1): When hashing or removing hosts, don\'t choke on
AATTrevoked markers and don\'t remove AATTcert-authority markers
* ssh(1): Don\'t fatal when hostname canonicalisation fails and
a ProxyCommand is in use; continue and allow the ProxyCommand
to connect anyway (e.g. to a host with a name outside the DNS
behind a bastion)
* scp(1): When copying local->remote fails during read, don\'t
send uninitialised heap to the remote end.
* sftp(1): Fix fatal \"el_insertstr failed\" errors when
tab-completing filenames with a single quote char somewhere
in the string
* ssh-keyscan(1): Scan for Ed25519 keys by default.
* ssh(1): When using VerifyHostKeyDNS with a DNSSEC resolver,
down-convert any certificate keys to plain keys and attempt
SSHFP resolution. Prevents a server from skipping SSHFP
lookup and forcing a new-hostkey dialog by offering only
certificate keys.
- OpenSSH 6.8
Potentially-incompatible changes:
* sshd(8): UseDNS now defaults to \'no\'. Configurations that
match against the client host name (via sshd_config or
authorized_keys) may need to re-enable it or convert to
matching against addresses.
New Features:
* Add FingerprintHash option to ssh(1) and sshd(8), and
equivalent command-line flags to the other tools to control
algorithm used for key fingerprints. The default changes from
MD5 to SHA256 and format from hex to base64.
Fingerprints now have the hash algorithm prepended. An
example of the new format:
SHA256:mVPwvezndPv/ARoIadVY98vAC0g+P/5633yTC4d/wXE Please
note that visual host keys will also be different.
* ssh(1), sshd(8): Experimental host key rotation support. Add
a protocol extension for a server to inform a client of all
its available host keys after authentication has completed.
The client may record the keys in known_hosts, allowing it to
upgrade to better host key algorithms and a server to
gracefully rotate its keys.
The client side of this is controlled by a UpdateHostkeys
config option (default off).
* ssh(1): Add a ssh_config HostbasedKeyType option to control
which host public key types are tried during host-based
authentication.
* ssh(1), sshd(8): fix connection-killing host key mismatch
errors when sshd offers multiple ECDSA keys of different
lengths.
* ssh(1): when host name canonicalisation is enabled, try to
parse host names as addresses before looking them up for
canonicalisation. fixes bz#2074 and avoiding needless DNS
lookups in some cases.
* ssh-keygen(1), sshd(8): Key Revocation Lists (KRLs) no longer
require OpenSSH to be compiled with OpenSSL support.
* ssh(1), ssh-keysign(8): Make ed25519 keys work for host based
authentication.
* sshd(8): SSH protocol v.1 workaround for the Meyer, et al,
Bleichenbacher Side Channel Attack. Fake up a bignum key
before RSA decryption.
* sshd(8): Remember which public keys have been used for
authentication and refuse to accept previously-used keys.
This allows AuthenticationMethods=publickey,publickey to
require that users authenticate using two _different_ public
keys.
* sshd(8): add sshd_config HostbasedAcceptedKeyTypes and
PubkeyAcceptedKeyTypes options to allow sshd to control what
public key types will be accepted. Currently defaults to all.
* sshd(8): Don\'t count partial authentication success as a
failure against MaxAuthTries.
* ssh(1): Add RevokedHostKeys option for the client to allow
text-file or KRL-based revocation of host keys.
* ssh-keygen(1), sshd(8): Permit KRLs that revoke certificates
by serial number or key ID without scoping to a particular
CA.
* ssh(1): Add a \"Match canonical\" criteria that allows
ssh_config Match blocks to trigger only in the second config
pass.
* ssh(1): Add a -G option to ssh that causes it to parse its
configuration and dump the result to stdout, similar to
\"sshd -T\".
* ssh(1): Allow Match criteria to be negated.
E.g. \"Match !host\".
* The regression test suite has been extended to cover more
OpenSSH features. The unit tests have been expanded and now
cover key exchange.
Bugfixes:
* ssh-keyscan(1): ssh-keyscan has been made much more robust
again servers that hang or violate the SSH protocol.
* ssh(1), ssh-keygen(1): Fix regression: Key path names were
being lost as comment fields.
* ssh(1): Allow ssh_config Port options set in the second
config parse phase to be applied (they were being ignored).
* ssh(1): Tweak config re-parsing with host canonicalisation - make
the second pass through the config files always run when host name
canonicalisation is enabled (and not whenever the host name
changes)
* ssh(1): Fix passing of wildcard forward bind addresses when
connection multiplexing is in use
* ssh-keygen(1): Fix broken private key conversion from
non-OpenSSH formats.
* ssh-keygen(1): Fix KRL generation bug when multiple CAs are
in use.
* Various fixes to manual pages
- OpenSSH 6.9
Security:
* ssh(1): when forwarding X11 connections with
ForwardX11Trusted=no, connections made after
ForwardX11Timeout expired could be permitted and no longer
subject to XSECURITY restrictions because of an ineffective
timeout check in ssh(1) coupled with \"fail open\" behaviour in
the X11 server when clients attempted connections with
expired credentials. This problem was reported by Jann Horn.
* ssh-agent(1): fix weakness of agent locking (ssh-add -x) to
password guessing by implementing an increasing failure
delay, storing a salted hash of the password rather than the
password itself and using a timing-safe comparison function
for verifying unlock attempts. This problem was reported by
Ryan Castellucci.
New Features:
* ssh(1), sshd(8): promote chacha20-poly1305AATTopenssh.com to be
the default cipher
* sshd(8): support admin-specified arguments to
AuthorizedKeysCommand
* sshd(8): add AuthorizedPrincipalsCommand that allows
retrieving authorized principals information from a
subprocess rather than a file.
* ssh(1), ssh-add(1): support PKCS#11 devices with external PIN
entry devices
* sshd(8): allow GSSAPI host credential check to be relaxed for
multihomed hosts via GSSAPIStrictAcceptorCheck option
* ssh-keygen(1): support \"ssh-keygen -lF hostname\" to search
known_hosts and print key hashes rather than full keys.
* ssh-agent(1): add -D flag to leave ssh-agent in foreground
without enabling debug mode
Bugfixes:
* ssh(1), sshd(8): deprecate legacy
SSH2_MSG_KEX_DH_GEX_REQUEST_OLD message and do not try to use
it against some 3rd-party SSH implementations that use it
(older PuTTY, WinSCP).
* Many fixes for problems caused by compile-time deactivation
of SSH1 support (including bz#2369)
* ssh(1), sshd(8): cap DH-GEX group size at 4Kbits for Cisco
implementations as some would fail when attempting to use
group sizes >4K
* ssh(1): fix out-of-bound read in EscapeChar configuration
option parsing
* sshd(8): fix application of PermitTunnel, LoginGraceTime,
AuthenticationMethods and StreamLocalBindMask options in
Match blocks
* ssh(1), sshd(8): improve disconnection message on TCP reset;
bz#2257
* ssh(1): remove failed remote forwards established by
muliplexing from the list of active forwards
* sshd(8): make parsing of authorized_keys \"environment=\"
options independent of PermitUserEnv being enabled
* sshd(8): fix post-auth crash with permitopen=none
* ssh(1), ssh-add(1), ssh-keygen(1): allow new-format private
keys to be encrypted with AEAD ciphers
* ssh(1): allow ListenAddress, Port and AddressFamily
configuration options to appear in any order
* sshd(8): check for and reject missing arguments for
VersionAddendum and ForceCommand
* ssh(1), sshd(8): don\'t treat unknown certificate extensions
as fatal
* ssh-keygen(1): make stdout and stderr output consistent
* ssh(1): mention missing DISPLAY environment in debug log when
X11 forwarding requested
* sshd(8): correctly record login when UseLogin is set
* sshd(8): Add some missing options to sshd -T output and fix
output of VersionAddendum and HostCertificate. bz#2346
* Document and improve consistency of options that accept a
\"none\" argument\" TrustedUserCAKeys, RevokedKeys (bz#2382),
AuthorizedPrincipalsFile (bz#2288)
* ssh(1): include remote username in debug output
* sshd(8): avoid compatibility problem with some versions of
Tera Term, which would crash when they received the hostkeys
notification message (hostkeys-00AATTopenssh.com)
* sshd(8): mention ssh-keygen -E as useful when comparing
legacy MD5 host key fingerprints
* ssh(1): clarify pseudo-terminal request behaviour and use
make manual language consistent
* ssh(1): document that the TERM environment variable is not
subject to SendEnv and AcceptEnv
- OpenSSH 7.0:
This focuses primarily on deprecating weak, legacy and/or
unsafe cryptography.
Security:
* sshd(8): OpenSSH 6.8 and 6.9 incorrectly set TTYs to be
world- writable. Local attackers may be able to write
arbitrary messages to logged-in users, including terminal
escape sequences. Reported by Nikolay Edigaryev.
* sshd(8): Portable OpenSSH only: Fixed a privilege separation
weakness related to PAM support. Attackers who could
successfully compromise the pre-authentication process for
remote code execution and who had valid credentials on the
host could impersonate other users. Reported by Moritz
Jodeit.
* sshd(8): Portable OpenSSH only: Fixed a use-after-free bug
related to PAM support that was reachable by attackers who
could compromise the pre-authentication process for remote
code execution. Also reported by Moritz Jodeit.
* sshd(8): fix circumvention of MaxAuthTries using keyboard-
interactive authentication. By specifying a long, repeating
keyboard-interactive \"devices\" string, an attacker could
request the same authentication method be tried thousands of
times in a single pass. The LoginGraceTime timeout in sshd(8)
and any authentication failure delays implemented by the
authentication mechanism itself were still applied. Found by
Kingcope.
Potentially-incompatible Changes:
* Support for the legacy SSH version 1 protocol is disabled by
default at compile time.
* Support for the 1024-bit diffie-hellman-group1-sha1 key
exchange is disabled by default at run-time. It may be
re-enabled using the instructions in README.legacy or
http://www.openssh.com/legacy.html
* Support for ssh-dss, ssh-dss-cert-
* host and user keys is
disabled by default at run-time. These may be re-enabled
using the instructions at http://www.openssh.com/legacy.html
* Support for the legacy v00 cert format has been removed.
* The default for the sshd_config(5) PermitRootLogin option has
changed from \"yes\" to \"prohibit-password\".
* PermitRootLogin=without-password/prohibit-password now bans
all interactive authentication methods, allowing only
public-key, hostbased and GSSAPI authentication (previously
it permitted keyboard-interactive and password-less
authentication if those were enabled).
New Features:
* ssh_config(5): add PubkeyAcceptedKeyTypes option to control
which public key types are available for user authentication.
* sshd_config(5): add HostKeyAlgorithms option to control which
public key types are offered for host authentications.
* ssh(1), sshd(8): extend Ciphers, MACs, KexAlgorithms,
HostKeyAlgorithms, PubkeyAcceptedKeyTypes and
HostbasedKeyTypes options to allow appending to the default
set of algorithms instead of replacing it. Options may now be
prefixed with a \'+\' to append to the default, e.g.
\"HostKeyAlgorithms=+ssh-dss\".
* sshd_config(5): PermitRootLogin now accepts an argument of
\'prohibit-password\' as a less-ambiguous synonym of \'without-
password\'.
Bugfixes:
* ssh(1), sshd(8): add compatability workarounds for Cisco and
more PuTTY versions.
* Fix some omissions and errors in the PROTOCOL and
PROTOCOL.mux documentation relating to Unix domain socket
forwarding
* ssh(1): Improve the ssh(1) manual page to include a better
description of Unix domain socket forwarding
* ssh(1), ssh-agent(1): skip uninitialised PKCS#11 slots,
fixing failures to load keys when they are present.
* ssh(1), ssh-agent(1): do not ignore PKCS#11 hosted keys that
wth empty CKA_ID
* sshd(8): clarify documentation for UseDNS option
- OpenSSH 7.1:
Security:
* sshd(8): OpenSSH 7.0 contained a logic error in
PermitRootLogin= prohibit-password/without-password that
could, depending on compile-time configuration, permit
password authentication to root while preventing other forms
of authentication. This problem was reported by Mantas
Mikulenas.
Bugfixes:
* ssh(1), sshd(8): add compatability workarounds for FuTTY
* ssh(1), sshd(8): refine compatability workarounds for WinSCP
* Fix a number of memory faults (double-free, free of
uninitialised memory, etc) in ssh(1) and ssh-keygen(1).
Reported by Mateusz Kocielski.
- OpenSSH 7.1p2:
* SECURITY: ssh(1): The OpenSSH client code between 5.4 and 7.1
contains experimential support for resuming SSH-connections
(roaming).
The matching server code has never been shipped, but the
client code was enabled by default and could be tricked by a
malicious server into leaking client memory to the server,
including private client user keys.
The authentication of the server host key prevents
exploitation by a man-in-the-middle, so this information leak
is restricted to connections to malicious or compromised
servers.
MITIGATION: For OpenSSH >= 5.4 the vulnerable code in the
client can be completely disabled by adding \'UseRoaming no\'
to the gobal ssh_config(5) file, or to user configuration in
~/.ssh/config, or by passing -oUseRoaming=no on the command
line.
PATCH: See below for a patch to disable this feature
(Disabling Roaming in the Source Code).
This problem was reported by the Qualys Security Advisory
team.
* SECURITY: Eliminate the fallback from untrusted
X11-forwarding to trusted forwarding for cases when the X
server disables the SECURITY extension. Reported by Thomas
Hoger.
* SECURITY: Fix an out of-bound read access in the packet
handling code. Reported by Ben Hawkes.
* PROTOCOL: Correctly interpret the \'first_kex_follows\' option
during the intial key exchange. Reported by Matt Johnston.
* Further use of explicit_bzero has been added in various
buffer handling code paths to guard against compilers
aggressively doing dead-store removal.
Potentially-incompatible changes:
* This release disables a number of legacy cryptographic
algorithms by default in ssh:
+ Several ciphers blowfish-cbc, cast128-cbc, all arcfour
variants and the rijndael-cbc aliases for AES.
+ MD5-based and truncated HMAC algorithms.
- OpenSSH 7.2:
Security:
* ssh(1), sshd(8): remove unfinished and unused roaming code
(was already forcibly disabled in OpenSSH 7.1p2).
* ssh(1): eliminate fallback from untrusted X11 forwarding to
trusted forwarding when the X server disables the SECURITY
extension.
* ssh(1), sshd(8): increase the minimum modulus size supported
for diffie-hellman-group-exchange to 2048 bits.
* sshd(8): pre-auth sandboxing is now enabled by default
(previous releases enabled it for new installations via
sshd_config).
New Features:
* all: add support for RSA signatures using SHA-256/512 hash
algorithms based on draft-rsa-dsa-sha2-256-03.txt and
draft-ssh-ext-info-04.txt.
* ssh(1): Add an AddKeysToAgent client option which can be set
to \'yes\', \'no\', \'ask\', or \'confirm\', and defaults to \'no\'.
When enabled, a private key that is used during
authentication will be added to ssh-agent if it is running
(with confirmation enabled if set to \'confirm\').
* sshd(8): add a new authorized_keys option \"restrict\" that
includes all current and future key restrictions
(no-
*-forwarding, etc.). Also add permissive versions of the
existing restrictions, e.g. \"no-pty\" -> \"pty\". This
simplifies the task of setting up restricted keys and ensures
they are maximally-restricted, regardless of any permissions
we might implement in the future.
* ssh(1): add ssh_config CertificateFile option to explicitly
list certificates. bz#2436
* ssh-keygen(1): allow ssh-keygen to change the key comment for
all supported formats.
* ssh-keygen(1): allow fingerprinting from standard input, e.g.
\"ssh-keygen -lf -\"
* ssh-keygen(1): allow fingerprinting multiple public keys in a
file, e.g. \"ssh-keygen -lf ~/.ssh/authorized_keys\" bz#1319
* sshd(8): support \"none\" as an argument for sshd_config
Foreground and ChrootDirectory. Useful inside Match blocks to
override a global default. bz#2486
* ssh-keygen(1): support multiple certificates (one per line)
and reading from standard input (using \"-f -\") for
\"ssh-keygen -L\"
* ssh-keyscan(1): add \"ssh-keyscan -c ...\" flag to allow
fetching certificates instead of plain keys.
* ssh(1): better handle anchored FQDNs (e.g. \'cvs.openbsd.org\')
in hostname canonicalisation - treat them as already
canonical and remove the trailing \'.\' before matching
ssh_config.
Bugfixes:
* sftp(1): existing destination directories should not
terminate recursive uploads (regression in openssh 6.8)
* ssh(1), sshd(8): correctly send back SSH2_MSG_UNIMPLEMENTED
replies to unexpected messages during key exchange.
* ssh(1): refuse attempts to set ConnectionAttempts=0, which
does not make sense and would cause ssh to print an
uninitialised stack variable.
* ssh(1): fix errors when attempting to connect to scoped IPv6
addresses with hostname canonicalisation enabled.
* sshd_config(5): list a couple more options usable in Match
blocks.
* sshd(8): fix \"PubkeyAcceptedKeyTypes +...\" inside a Match
block.
* ssh(1): expand tilde characters in filenames passed to -i
options before checking whether or not the identity file
exists. Avoids confusion for cases where shell doesn\'t expand
(e.g. \"-i ~/file\" vs. \"-i~/file\").
* ssh(1): do not prepend \"exec\" to the shell command run by
\"Match exec\" in a config file, which could cause some
commands to fail in certain environments.
* ssh-keyscan(1): fix output for multiple hosts/addrs on one
line when host hashing or a non standard port is in use
* sshd(8): skip \"Could not chdir to home directory\" message
when ChrootDirectory is active.
* ssh(1): include PubkeyAcceptedKeyTypes in ssh -G config dump.
* sshd(8): avoid changing TunnelForwarding device flags if they
are already what is needed; makes it possible to use tun/tap
networking as non-root user if device permissions and
interface flags are pre-established
* ssh(1), sshd(8): RekeyLimits could be exceeded by one packet.
* ssh(1): fix multiplexing master failure to notice client
exit.
* ssh(1), ssh-agent(1): avoid fatal() for PKCS11 tokens that
present empty key IDs.
* sshd(8): avoid printf of NULL argument.
* ssh(1), sshd(8): allow RekeyLimits larger than 4GB.
* ssh-keygen(1): sshd(8): fix several bugs in (unused) KRL
signature support.
* ssh(1), sshd(8): fix connections with peers that use the key
exchange guess feature of the protocol.
* sshd(8): include remote port number in log messages.
* ssh(1): don\'t try to load SSHv1 private key when compiled
without SSHv1 support.
* ssh-agent(1), ssh(1): fix incorrect error messages during key
loading and signing errors.
* ssh-keygen(1): don\'t leave empty temporary files when
performing known_hosts file edits when known_hosts doesn\'t
exist.
* sshd(8): correct packet format for tcpip-forward replies for
requests that don\'t allocate a port
* ssh(1), sshd(8): fix possible hang on closed output.
* ssh(1): expand %i in ControlPath to UID.
* ssh(1), sshd(8): fix return type of openssh_RSA_verify.
* ssh(1), sshd(8): fix some option parsing memory leaks.
* ssh(1): add a some debug output before DNS resolution; it\'s a
place where ssh could previously silently stall in cases of
unresponsive DNS servers.
* ssh(1): remove spurious newline in visual hostkey.
* ssh(1): fix printing (ssh -G ...) of HostKeyAlgorithms=+...
* ssh(1): fix expansion of HostkeyAlgorithms=+...
Documentation:
* ssh_config(5), sshd_config(5): update default algorithm lists
to match current reality.
* ssh(1): mention -Q key-plain and -Q key-cert query options.
* sshd_config(8): more clearly describe what
AuthorizedKeysFile=none does.
* ssh_config(5): better document ExitOnForwardFailure.
* sshd(5): mention internal DH-GEX fallback groups in manual.
* sshd_config(5): better description for MaxSessions option.
Portability:
* sshd(8): fix multiple authentication using S/Key.
- OpenSSH 7.2p2:
Security:
* sshd(8): sanitise X11 authentication credentials to avoid
xauth command injection when X11Forwarding is enabled.

Security:
* sshd(8): when using environment passing with a sshd_config(5)
AcceptEnv pattern with a wildcard. OpenSSH prior to 6.6 could
be tricked into accepting any enviornment variable that
contains the characters before the wildcard character.
Features since 6.5p1:
* ssh(1), sshd(8): removal of the J-PAKE authentication code,
which was experimental, never enabled and has been
unmaintained for some time.
* ssh(1): skip \'exec\' clauses other clauses predicates failed
to match while processing Match blocks.
* ssh(1): if hostname canonicalisation is enabled and results
in the destination hostname being changed, then re-parse
ssh_config(5) files using the new destination hostname. This
gives \'Host\' and \'Match\' directives that use the expanded
hostname a chance to be applied.
Bugfixes:
* ssh(1): avoid spurious \"getsockname failed: Bad file
descriptor\" in ssh -W. bz#2200, debian#738692
* sshd(8): allow the shutdown(2) syscall in seccomp-bpf and
systrace sandbox modes, as it is reachable if the connection
is terminated during the pre-auth phase.
* ssh(1), sshd(8): fix unsigned overflow that in SSH protocol 1
bignum parsing. Minimum key length checks render this bug
unexploitable to compromise SSH 1 sessions.
* sshd_config(5): clarify behaviour of a keyword that appears
in multiple matching Match blocks. bz#2184
* ssh(1): avoid unnecessary hostname lookups when
canonicalisation is disabled. bz#2205
* sshd(8): avoid sandbox violation crashes in GSSAPI code by
caching the supported list of GSSAPI mechanism OIDs before
entering the sandbox. bz#2107
* ssh(1): fix possible crashes in SOCKS4 parsing caused by
assumption that the SOCKS username is nul-terminated.
* ssh(1): fix regression for UsePrivilegedPort=yes when
BindAddress is not specified.
* ssh(1), sshd(8): fix memory leak in ECDSA signature
verification.
* ssh(1): fix matching of \'Host\' directives in ssh_config(5)
files to be case-insensitive again (regression in 6.5).

- Update to 6.5p1
Features since 6.4p1:
* ssh(1), sshd(8): support for key exchange using ECDH in
Daniel Bernstein\'s Curve25519; default when both the client
and server support it.
* ssh(1), sshd(8): support for Ed25519 as a public key type fo
rboth server and client. Ed25519 is an EC signature offering
better security than ECDSA and DSA and good performance.
* Add a new private key format that uses a bcrypt KDF to better
protect keys at rest. Used unconditionally for Ed25519 keys,
on demand for other key types via the -o ssh-keygen(1)
option. Intended to become default in the near future.
Details documented in PROTOCOL.key.
* ssh(1), sshd(8): new transport cipher
\"chacha20-poly1305AATTopenssh.com\" combining Daniel Bernstein\'s
ChaCha20 stream cipher and Poly1305 MAC to build an
authenticated encryption mode. Details documented
PROTOCOL.chacha20poly1305.
* ssh(1), sshd(8): refuse RSA keys from old proprietary clients
and servers that use the obsolete RSA+MD5 signature scheme.
It will still be possible to connect with these
clients/servers but only DSA keys will be accepted, and
OpenSSH will refuse connection entirely in a future release.
* ssh(1), sshd(8): refuse old proprietary clients and servers
that use a weaker key exchange hash calculation.
* ssh(1): increase the size of the Diffie-Hellman groups
requested for each symmetric key size. New values from NIST
Special Publication 800-57 with the upper limit specified by
RFC4419.
* ssh(1), ssh-agent(1): support pkcs#11 tokens that only
provide X.509 certs instead of raw public keys (requested as
bz#1908).
* ssh(1): new ssh_config(5) \"Match\" keyword that allows
conditional configuration to be applied by matching on
hostname, user and result of arbitrary commands.
* ssh(1): support for client-side hostname canonicalisation
using a set of DNS suffixes and rules in ssh_config(5). This
allows unqualified names to be canonicalised to
fully-qualified domain names to eliminate ambiguity when
looking up keys in known_hosts or checking host certificate
names.
* sftp-server(8): ability to whitelist and/or blacklist sftp
protocol requests by name.
* sftp-server(8): sftp \"fsyncAATTopenssh.com\" to support calling
fsync(2) on an open file handle.
* sshd(8): ssh_config(5) PermitTTY to disallow TTY allocation,
mirroring the longstanding no-pty authorized_keys option.
* ssh(1): ssh_config ProxyUseFDPass option that supports the
use of ProxyCommands that establish a connection and then
pass a connected file descriptor back to ssh(1). This allows
the ProxyCommand to exit rather than staying around to
transfer data.
Bugfixes since 6.4p1:
* ssh(1), sshd(8): fix potential stack exhaustion caused by
nested certificates.
* ssh(1): bz#1211: make BindAddress work with
UsePrivilegedPort.
* sftp(1): bz#2137: fix the progress meter for resumed
transfer.
* ssh-add(1): bz#2187: do not request smartcard PIN when
removing keys from ssh-agent.
* sshd(8): bz#2139: fix re-exec fallback when original sshd
binary cannot be executed.
* ssh-keygen(1): make relative-specified certificate expiry
times relative to current time and not the validity start
time.
* sshd(8): bz#2161: fix AuthorizedKeysCommand inside a Match
block.
* sftp(1): bz#2129: symlinking a file would incorrectly
canonicalise the target path.
* ssh-agent(1): bz#2175: fix a use-after-free in the PKCS#11
agent helper executable.
* sshd(8): improve logging of sessions to include the user
name, remote host and port, the session type (shell, command,
etc.) and allocated TTY (if any).
* sshd(8): bz#1297: tell the client (via a debug message) when
their preferred listen address has been overridden by the
server\'s GatewayPorts setting.
* sshd(8): bz#2162: include report port in bad protocol banner
message.
* sftp(1): bz#2163: fix memory leak in error path in
do_readdir().
* sftp(1): bz#2171: don\'t leak file descriptor on error.
* sshd(8): include the local address and port in \"Connection
from ...\" message (only shown at loglevel>=verbose).

Fri Jan 24 13:00:00 2014 pcernyAATTsuse.com
- Update to 6.4p1
Features since 6.2p2:
* ssh-agent(1) support in sshd(8); allows encrypted hostkeys, or
hostkeys on smartcards.
* ssh(1)/sshd(8): allow optional time-based rekeying via a
second argument to the existing RekeyLimit option. RekeyLimit
is now supported in sshd_config as well as on the client.
* sshd(8): standardise logging of information during user
authentication.
* The presented key/cert and the remote username (if available)
is now logged in the authentication success/failure message on
the same log line as the local username, remote host/port and
protocol in use. Certificates contents and the key
fingerprint of the signing CA are logged too.
* ssh(1) ability to query what cryptographic algorithms are
supported in the binary.
* ssh(1): ProxyCommand=- for cases where stdin and stdout
already point to the proxy.
* ssh(1): allow IdentityFile=none
* ssh(1)/sshd(8): -E option to append debugging logs to a
specified file instead of stderr or syslog.
* sftp(1): support resuming partial downloads with the \"reget\"
command and on the sftp commandline or on the \"get\"
commandline with the \"-a\" (append) option.
* ssh(1): \"IgnoreUnknown\" configuration option to selectively
suppress errors arising from unknown configuration directives.
* sshd(8): support for submethods to be appended to required
authentication methods listed via AuthenticationMethods.
Bugfixes since 6.2p2:
* sshd(8): fix refusal to accept certificate if a key of a
different type to the CA key appeared in authorized_keys
before the CA key.
* ssh(1)/ssh-agent(1)/sshd(8): Use a monotonic time source for
timers so that things like keepalives and rekeying will work
properly over clock steps.
* sftp(1): update progressmeter when data is acknowledged, not
when it\'s sent. bz#2108
* ssh(1)/ssh-keygen(1): improve error messages when the current
user does not exist in /etc/passwd; bz#2125
* ssh(1): reset the order in which public keys are tried after
partial authentication success.
* ssh-agent(1): clean up socket files after SIGINT when in debug
mode; bz#2120
* ssh(1) and others: avoid confusing error messages in the case
of broken system resolver configurations; bz#2122
* ssh(1): set TCP nodelay for connections started with -N;
bz#2124

Tue Nov 13 13:00:00 2012 meissnerAATTsuse.com
- Updated to 6.1p1, a bugfix release
Features:
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
* ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
* sshd(8): Allow the sshd_config PermitOpen directive to accept \"none\" as
an argument to refuse all port-forwarding requests.
* sshd(8): Support \"none\" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add \"VersionAddendum\" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.
Bugfixes:
* ssh(1)/sshd(8): Don\'t spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025
* ssh(1): Delay setting tty_flag so RequestTTY options are correctly
picked up. bz#1995
* sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
on platforms that use login_cap.
Portable OpenSSH:
* sshd(8): Allow sshd pre-auth sandboxing to fall-back to the rlimit
sandbox from the Linux SECCOMP filter sandbox when the latter is
not available in the kernel.
* ssh(1): Fix NULL dereference when built with LDNS and using DNSSEC to
retrieve a CNAME SSHFP record.
* Fix cross-compilation problems related to pkg-config. bz#1996

- Update to 5.7p1
* Implement Elliptic Curve Cryptography modes for key exchange (ECDH)
and host/user keys (ECDSA) as specified by RFC5656.
* sftp(1)/sftp-server(8): add a protocol extension to support a hard
link operation.
* scp(1): Add a new -3 option to scp: Copies between two remote hosts
are transferred through the local host.
* ssh(1): automatically order the hostkeys requested by the client
based on which hostkeys are already recorded in known_hosts.
* ssh(1)/sshd(8): add a new IPQoS option to specify arbitrary
TOS/DSCP/QoS values instead of hardcoding lowdelay/throughput.
* sftp(1): the sftp client is now significantly faster at performing
directory listings, using OpenBSD glob(3) extensions to preserve
the results of stat(3) operations performed in the course of its
execution rather than performing expensive round trips to fetch
them again afterwards.
* ssh(1): \"atomically\" create the listening mux socket by binding it on
a temporary name and then linking it into position after listen() has
succeeded.
* ssh(1)/sshd(8): add a KexAlgorithms knob to the client and server
configuration to allow selection of which key exchange methods are
used by ssh(1) and sshd(8) and their order of preference.
* sftp(1)/scp(1): factor out bandwidth limiting code from scp(1) into
a generic bandwidth limiter that can be attached using the atomicio
callback mechanism and use it to add a bandwidth limit option to
sftp(1).
* Support building against openssl-1.0.0a.
* Bug fixes.
- Remove patches that are now upstream:
* openssh-5.6p1-tmpdir.diff
* openssh-linux-new-oomkill.patch
- Add upstream patch to fix build with SELinux enabled.

- update to 5.6p1
* Added a ControlPersist option to ssh_config(5) that automatically
starts a background ssh(1) multiplex master when connecting.
* Hostbased authentication may now use certificate host keys.
* ssh-keygen(1) now supports signing certificate using a CA key that
has been stored in a PKCS#11 token.
* ssh(1) will now log the hostname and address that we connected to at
LogLevel=verbose after authentication is successful to mitigate
\"phishing\" attacks by servers with trusted keys that accept
authentication silently and automatically before presenting fake
password/passphrase prompts.
* Expand %h to the hostname in ssh_config Hostname options.
* Allow ssh-keygen(1) to import (-i) and export (-e) of PEM and PKCS#8
keys in addition to RFC4716 (SSH.COM) encodings via a new -m option
* sshd(8) will now queue debug messages for bad ownership or
permissions on the user\'s keyfiles encountered during authentication
and will send them after authentication has successfully completed.
* ssh(1) connection multiplexing now supports remote forwarding with
dynamic port allocation and can report the allocated port back to
the user
* sshd(8) now supports indirection in matching of principal names
listed in certificates.
* sshd(8) now has a new AuthorizedPrincipalsFile option to specify a
file containing a list of names that may be accepted in place of the
username when authorizing a certificate trusted via the
sshd_config(5) TrustedCAKeys option.
* Additional sshd_config(5) options are now valid inside Match blocks
* Revised the format of certificate keys.
* bugfixes

Thu Mar 25 13:00:00 2010 meissnerAATTsuse.de
- Enable VisualHostKey (ascii art of the hostkey fingerprint) and
HashHostKeys (hardening measure to make them unusable for worms/malicious
users for further host hopping).
Tue Mar 23 13:00:00 2010 anickaAATTsuse.cz
- update to 5.4p1
* After a transition period of about 10 years, this release disables
SSH protocol 1 by default. Clients and servers that need to use the
legacy protocol must explicitly enable it in ssh_config / sshd_config
or on the command-line.
* Remove the libsectok/OpenSC-based smartcard code and add support for
PKCS#11 tokens. This support is automatically enabled on all
platforms that support dlopen(3) and was inspired by patches written
by Alon Bar-Lev. Details in the ssh(1) and ssh-add(1) manpages.
* Add support for certificate authentication of users and hosts using a
new, minimal OpenSSH certificate format (not X.509). Certificates
contain a public key, identity information and some validity
constraints and are signed with a standard SSH public key using
ssh-keygen(1). CA keys may be marked as trusted in authorized_keys
or via a TrustedUserCAKeys option in sshd_config(5) (for user
authentication), or in known_hosts (for host authentication).
Documentation for certificate support may be found in ssh-keygen(1),
sshd(8) and ssh(1) and a description of the protocol extensions in
PROTOCOL.certkeys.
* Added a \'netcat mode\' to ssh(1): \"ssh -W host:port ...\" This connects
stdio on the client to a single port forward on the server. This
allows, for example, using ssh as a ProxyCommand to route connections
via intermediate servers. bz#1618
* Add the ability to revoke keys in sshd(8) and ssh(1). User keys may
be revoked using a new sshd_config(5) option \"RevokedKeys\". Host keys
are revoked through known_hosts (details in the sshd(8) man page).
Revoked keys cannot be used for user or host authentication and will
trigger a warning if used.
* Rewrite the ssh(1) multiplexing support to support non-blocking
operation of the mux master, improve the resilience of the master to
malformed messages sent to it by the slave and add support for
requesting port- forwardings via the multiplex protocol. The new
stdio-to-local forward mode (\"ssh -W host:port ...\") is also
supported. The revised multiplexing protocol is documented in the
file PROTOCOL.mux in the source distribution.
* Add a \'read-only\' mode to sftp-server(8) that disables open in write
mode and all other fs-modifying protocol methods. bz#430
* Allow setting an explicit umask on the sftp-server(8) commandline to
override whatever default the user has. bz#1229
* Many improvements to the sftp(1) client, many of which were
implemented by Carlos Silva through the Google Summer of Code
program:
- Support the \"-h\" (human-readable units) flag for ls
- Implement tab-completion of commands, local and remote filenames
- Support most of scp(1)\'s commandline arguments in sftp(1), as a
first step towards making sftp(1) a drop-in replacement for scp(1).
Note that the rarely-used \"-P sftp_server_path\" option has been
moved to \"-D sftp_server_path\" to make way for \"-P port\" to match
scp(1).
- Add recursive transfer support for get/put and on the commandline
* New RSA keys will be generated with a public exponent of RSA_F4 ==
(2
*
*16)+1 == 65537 instead of the previous value 35.
* Passphrase-protected SSH protocol 2 private keys are now protected
with AES-128 instead of 3DES. This applied to newly-generated keys
as well as keys that are reencrypted (e.g. by changing their
passphrase).
