* SUSE Linux Enterprise High Performance Computing 12 SP5
* SUSE Linux Enterprise Server 12 SP5
* SUSE Linux Enterprise Server 12 SP5 LTSS
* SUSE Linux Enterprise Server 12 SP5 LTSS Extended Security
* SUSE Linux Enterprise Server for SAP Applications 12 SP5
An update that solves one vulnerability and has eight security fixes can now be
installed.
## Description:
This update for openssh8.4 fixes the following issues:
* CVE-2025-26465: Fixed a MitM attack against OpenSSH's VerifyHostKeyDNS-
enabled client (bsc#1237040).
Other bugfixes:
* Fix usage of local accelerator cards via openssl-ibmca (bsc#1216474,
bsc#1218871).
* Add patches from upstream to change the default value of UpdateHostKeys to
Yes (unless VerifyHostKeyDNS is enabled) (bsc#1222831).
* Fix hostbased ssh login failing occasionally with "signature
unverified:
incorrect signature" by fixing a typo in patch (bsc#1221123).
* For now we don't ship the ssh-keycat command, but we need the patch for
the
other SELinux infrastructure (bsc#1214788).
* Attempts to mitigate instances of secrets lingering in memory after a
session exits (bsc#1213004, bsc#1213008, bsc#1186673).
## Patch Instructions:
To install this SUSE update use the SUSE recommended installation methods like
YaST online_update or "zypper patch".
