- Update to openssh 9.8p1:
* No changes for askpass, see main package changelog for
details.
- Add patch to fix sshd not logging in the audit failed login
attempts (submitted to upstream in
https://github.com/openssh/openssh-portable/pull/516):
* fix-audit-fail-attempt.patch
- Use --enable-dsa-keys when building openssh. It's required if
the user sets the crypto-policy mode to LEGACY, where DSA keys
should be allowed. The option was added by upstream in 9.7 and
set to disabled by default.
- These two changes fix 2 of the 3 issues reported in bsc#1229650.
- Fix a dbus connection leaked in the logind patch that was
missing a sd_bus_unref call (found by Matthias Gerstner):
* logind_set_tty.patch
- Add a patch that fixes a small memory leak when parsing the
subsystem configuration option:
* fix-memleak-in-process_server_config_line_depth.patch
- Update to openssh 9.8p1:
= Security
* 1) Race condition in sshd(8) (bsc#1226642, CVE-2024-6387).
A critical vulnerability in sshd(8) was present in Portable
OpenSSH versions between 8.5p1 and 9.7p1 (inclusive) that may
allow arbitrary code execution with root privileges.
Successful exploitation has been demonstrated on 32-bit
Linux/glibc systems with ASLR. Under lab conditions, the attack
requires on average 6-8 hours of continuous connections up to

There are following changes in default settings of ssh client and server:
* Accepting and sending of locale environment variables in protocol 2 is
enabled.
* PAM authentication is enabled and mostly even required, do not turn it off.
* In SLE15, root authentiation with password is enabled by default
(PermitRootLogin yes).
NOTE: this has security implications and is only done in order to not change
behaviour of the server in an update. We strongly suggest setting this option
either "prohibit-password" or even better to "no" (which disables direct
remote root login entirely).
* DSA authentication is enabled by default for maximum compatibility.
NOTE: do not use DSA authentication since it is being phased out for a reason
- the size of DSA keys is limited by the standard to 1024 bits which cannot
be considered safe any more.
* Accepting all RFC4419 specified DH group parameters. See KexDHMin in
ssh_config and sshd_config manual pages.
