medium Nessus Plugin ID 216960

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2025:0744-1 advisory.

- 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).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
