Changelog for krb5-server-1.20-2.1.x86_64.rpm :

* Sun May 29 2022 Dirk Müller - update to 1.20.0:
* Added a \"disable_pac\" realm relation to suppress adding PAC authdata to tickets, for realms which do not need to support S4U requests.
* Most credential cache types will use atomic replacement when a cache is reinitialized using kinit or refreshed from the client keytab.
* kprop can now propagate databases with a dump size larger than 4GB, if both the client and server are upgraded.
* kprop can now work over NATs that change the destination IP address, if the client is upgraded.
* Updated the KDB interface. The sign_authdata() method is replaced with the issue_pac() method, allowing KDB modules to add logon info and other buffers to the PAC issued by the KDC.
* Host-based initiator names are better supported in the GSS krb5 mechanism.
* Replaced AD-SIGNEDPATH authdata with minimal PACs.
* To avoid spurious replay errors, password change requests will not be attempted over UDP until the attempt over TCP fails.
* PKINIT will sign its CMS messages with SHA-256 instead of SHA-1.
* Updated all code using OpenSSL to be compatible with OpenSSL 3.
* Reorganized the libk5crypto build system to allow the OpenSSL back-end to pull in material from the builtin back-end depending on the OpenSSL version.
* Simplified the PRNG logic to always use the platform PRNG.
* Converted the remaining Tcl tests to Python.
* Sat Apr 09 2022 Dirk Müller - update to 1.19.3 (bsc#1189929, CVE-2021-37750):
* Fix a denial of service attack against the KDC [CVE-2021-37750].
* Fix KDC null deref on TGS inner body null server
* Fix conformance issue in GSSAPI tests
* Thu Jan 27 2022 David Mulder - Resolve \"Credential cache directory /run/user/0/krb5cc does not exist while opening default credentials cache\" by using a kernel keyring instead of a dir cache; (bsc#1109830);
* Thu Sep 30 2021 Johannes Segitz - Added hardening to systemd services; (bsc#1181400);
* Mon Aug 30 2021 Samuel Cabrero - Fix KDC null pointer dereference via a FAST inner body that lacks a server field; (CVE-2021-37750); (bsc#1189929);- Added patches:
* 0009-Fix-KDC-null-deref-on-TGS-inner-body-null-server.patch
* Mon Aug 02 2021 Samuel Cabrero - Update to 1.19.2
* Fix a denial of service attack against the KDC encrypted challenge code; (CVE-2021-36222);
* Fix a memory leak when gss_inquire_cred() is called without a credential handle.
* Mon May 03 2021 Rodrigo Lourenço - Build with full Cyrus SASL support
* Negotiating SASL credentials with an EXTERNAL bind mechanism requires interaction. Kerberos provides its own interaction function that skips all interaction, thus preventing the mechanism from working.
* Thu Apr 22 2021 Samuel Cabrero - Use /run instead of /var/run for daemon PID files; (bsc#1185163);
* Wed Apr 07 2021 Dirk Müller - do not own %sbindir, it comes from filesystem package
* Fri Feb 19 2021 Samuel Cabrero - Update to 1.19.1
* Fix a linking issue with Samba.
* Better support multiple pkinit_identities values by checking whether certificates can be loaded for each value.
* Fri Feb 05 2021 Samuel Cabrero - Update to 1.19 Administrator experience
* When a client keytab is present, the GSSAPI krb5 mech will refresh credentials even if the current credentials were acquired manually.
* It is now harder to accidentally delete the K/M entry from a KDB. Developer experience
* gss_acquire_cred_from() now supports the \"password\" and \"verify\" options, allowing credentials to be acquired via password and verified using a keytab key.
* When an application accepts a GSS security context, the new GSS_C_CHANNEL_BOUND_FLAG will be set if the initiator and acceptor both provided matching channel bindings.
* Added the GSS_KRB5_NT_X509_CERT name type, allowing S4U2Self requests to identify the desired client principal by certificate.
* PKINIT certauth modules can now cause the hw-authent flag to be set in issued tickets.
* The krb5_init_creds_step() API will now issue the same password expiration warnings as krb5_get_init_creds_password(). Protocol evolution
* Added client and KDC support for Microsoft\'s Resource-Based Constrained Delegation, which allows cross-realm S4U2Proxy requests. A third-party database module is required for KDC support.
* kadmin/admin is now the preferred server principal name for kadmin connections, and the host-based form is no longer created by default. The client will still try the host-based form as a fallback.
* Added client and server support for Microsoft\'s KERB_AP_OPTIONS_CBT extension, which causes channel bindings to be required for the initiator if the acceptor provided them. The client will send this option if the client_aware_gss_bindings profile option is set. User experience
* kinit will now issue a warning if the des3-cbc-sha1 encryption type is used in the reply. This encryption type will be deprecated and removed in future releases.
* Added kvno flags --out-cache, --no-store, and --cached-only (inspired by Heimdal\'s kgetcred).
* Thu Nov 19 2020 Samuel Cabrero - Update to 1.18.3
* Fix a denial of service vulnerability when decoding Kerberos protocol messages; (CVE-2020-28196); (bsc#1178512);
* Fix a locking issue with the LMDB KDB module which could cause KDC and kadmind processes to lose access to the database.
* Fix an assertion failure when libgssapi_krb5 is repeatedly loaded and unloaded while libkrb5support remains loaded.
* Tue Jul 07 2020 Andreas Schwab - Don\'t fail if %{_lto_cflags} is empty
* Fri Jun 12 2020 Dominique Leuenberger - Do not mangle libexecdir, bindir, sbindir and datadir: there is no reasonable justification to step out of the defaults. + No longer install csh/sh profiles into /etc/profiles.d: as we not install to default paths, there is no need to further inject paths into $PATH; also, now sbin binaries are only in path for admin users.
* Fri May 29 2020 Samuel Cabrero - Update to 1.18.2
* Fix a SPNEGO regression where an acceptor using the default credential would improperly filter mechanisms, causing a negotiation failure.
* Fix a bug where the KDC would fail to issue tickets if the local krbtgt principal\'s first key has a single-DES enctype.
* Add stub functions to allow old versions of OpenSSL libcrypto to link against libkrb5.
* Fix a NegoEx bug where the client name and delegated credential might not be reported.
* Thu May 28 2020 Samuel Cabrero - Update logrotate script, call systemd to reload the services instead of init-scripts. (boo#1169357)
* Tue May 26 2020 Christophe Giboudeaux - Don\'t add the lto flags to the public link options. (boo#1172038)
* Mon May 04 2020 Samuel Cabrero - Upgrade to 1.18.1
* Fix a crash when qualifying short hostnames when the system has no primary DNS domain.
* Fix a regression when an application imports \"serviceAATT\" as a GSS host-based name for its acceptor credential handle.
* Fix KDC enforcement of auth indicators when they are modified by the KDB module.
* Fix removal of require_auth string attributes when the LDAP KDB module is used.
* Fix a compile error when building with musl libc on Linux.
* Fix a compile error when building with gcc 4.x.
* Change the KDC constrained delegation precedence order for consistency with Windows KDCs.- Remove 0009-Fix-null-dereference-qualifying-short-hostnames.patch
* Wed Apr 29 2020 Dominique Leuenberger - Use %_tmpfilesdir instead of the wrong %_libexecdir/tmpfiles.d notation: libexecdir is likely changing away from /usr/lib to /usr/libexec.
* Wed Mar 25 2020 Samuel Cabrero - Fix segfault in k5_primary_domain; (bsc#1167620);- Added patches:
* 0009-Fix-null-dereference-qualifying-short-hostnames.patch
* Tue Feb 25 2020 Tomáš Chvátal - Remove cruft to support distributions older than SLE 12- Use macros where applicable- Switch to pkgconfig style dependencies
* Mon Feb 17 2020 Samuel Cabrero - Upgrade to 1.18 Administrator experience:
* Remove support for single-DES encryption types.
* Change the replay cache format to be more efficient and robust. Replay cache filenames using the new format end with \".rcache2\" by default.
* setuid programs will automatically ignore environment variables that normally affect krb5 API functions, even if the caller does not use krb5_init_secure_context().
* Add an \"enforce_ok_as_delegate\" krb5.conf relation to disable credential forwarding during GSSAPI authentication unless the KDC sets the ok-as-delegate bit in the service ticket.
* Use the permitted_enctypes krb5.conf setting as the default value for default_tkt_enctypes and default_tgs_enctypes. Developer experience:
* Implement krb5_cc_remove_cred() for all credential cache types.
* Add the krb5_pac_get_client_info() API to get the client account name from a PAC. Protocol evolution:
* Add KDC support for S4U2Self requests where the user is identified by X.509 certificate. (Requires support for certificate lookup from a third-party KDB module.)
* Remove support for an old (\"draft 9\") variant of PKINIT.
* Add support for Microsoft NegoEx. (Requires one or more third-party GSS modules implementing NegoEx mechanisms.) User experience:
* Add support for \"dns_canonicalize_hostname=fallback\", causing host-based principal names to be tried first without DNS canonicalization, and again with DNS canonicalization if the un-canonicalized server is not found.
* Expand single-component hostnames in host-based principal names when DNS canonicalization is not used, adding the system\'s first DNS search path as a suffix. Add a \"qualify_shortname\" krb5.conf relation to override this suffix or disable expansion.
* Honor the transited-policy-checked ticket flag on application servers, eliminating the requirement to configure capaths on servers in some scenarios. Code quality:
* The libkrb5 serialization code (used to export and import krb5 GSS security contexts) has been simplified and made type-safe.
* The libkrb5 code for creating KRB-PRIV, KRB-SAFE, and KRB-CRED messages has been revised to conform to current coding practices.
* The test suite has been modified to work with macOS System Integrity Protection enabled.
* The test suite incorporates soft-pkcs11 so that PKINIT PKCS11 support can always be tested.- Updated patches:
* 0002-krb5-1.9-manpaths.patch
* 0004-krb5-1.6.3-gssapi_improve_errormessages.patch
* 0005-krb5-1.6.3-ktutil-manpage.patch
* 0006-krb5-1.12-api.patch- Renamed patches:
* 0001-krb5-1.12-pam.patch => 0001-ksu-pam-integration.patch
* 0003-krb5-1.12-buildconf.patch => 0003-Adjust-build-configuration.patch
* 0008-krb5-1.12-selinux-label.patch => 0007-SELinux-integration.patch
* 0009-krb5-1.9-debuginfo.patch => 0008-krb5-1.9-debuginfo.patch- Deleted patches:
* 0007-krb5-1.12-ksu-path.patch
* Thu Dec 12 2019 Samuel Cabrero - Upgrade to 1.17.1
* Fix a bug preventing \"addprinc -randkey -kvno\" from working in kadmin.
* Fix a bug preventing time skew correction from working when a KCM credential cache is used.
* Mon Aug 05 2019 Samuel Cabrero - Integrate pam_keyinit pam module, ksu-pam.d; (bsc#1081947); (bsc#1144047);
* Wed Jul 24 2019 matthias.gerstnerAATTsuse.com- removal of SuSEfirewall2 service, since SuSEfirewall2 has been replaced by firewalld, see [1]. [1]: https://lists.opensuse.org/opensuse-factory/2019-01/msg00490.html
* Tue May 07 2019 Samuel Cabrero - Move LDAP schema files from /usr/share/doc/packages/krb5 to /usr/share/kerberos/ldap; (bsc#1134217);
* Wed Feb 13 2019 Jan Engelhardt - Replace old $RPM_
* shell vars
* Mon Jan 14 2019 Samuel Cabrero - Upgrade to 1.17. Major changes: Administrator experience:
* A new Kerberos database module using the Lightning Memory-Mapped Database library (LMDB) has been added. The LMDB KDB module should be more performant and more robust than the DB2 module, and may become the default module for new databases in a future release.
* \"kdb5_util dump\" will no longer dump policy entries when specific principal names are requested. Developer experience:
* The new krb5_get_etype_info() API can be used to retrieve enctype, salt, and string-to-key parameters from the KDC for a client principal.
* The new GSS_KRB5_NT_ENTERPRISE_NAME name type allows enterprise principal names to be used with GSS-API functions.
* KDC and kadmind modules which call com_err() will now write to the log file in a format more consistent with other log messages.
* Programs which use large numbers of memory credential caches should perform better. Protocol evolution:
* The SPAKE pre-authentication mechanism is now supported. This mechanism protects against password dictionary attacks without requiring any additional infrastructure such as certificates. SPAKE is enabled by default on clients, but must be manually enabled on the KDC for this release.
* PKINIT freshness tokens are now supported. Freshness tokens can protect against scenarios where an attacker uses temporary access to a smart card to generate authentication requests for the future.
* Password change operations now prefer TCP over UDP, to avoid spurious error messages about replays when a response packet is dropped.
* The KDC now supports cross-realm S4U2Self requests when used with a third-party KDB module such as Samba\'s. The client code for cross-realm S4U2Self requests is also now more robust (CVE-2018-20217). User experience:
* The new ktutil addent -f flag can be used to fetch salt information from the KDC for password-based keys.
* The new kdestroy -p option can be used to destroy a credential cache within a collection by client principal name.
* The Kerberos man page has been restored, and documents the environment variables that affect programs using the Kerberos library. Code quality:
* Python test scripts now use Python 3.
* Python test scripts now display markers in verbose output, making it easier to find where a failure occurred within the scripts.
* The Windows build system has been simplified and updated to work with more recent versions of Visual Studio. A large volume of unused Windows-specific code has been removed. Visual Studio 2013 or later is now required.- Use systemd-tmpfiles to create files under /var/lib/kerberos, required by transactional updates; (bsc#1100126);- Rename patches:
