<p>An update that solves one vulnerability and has eight security fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for openssh8.4 fixes the following issues:</p>
<ul>
<li>CVE-2025-26465: Fixed a MitM attack against OpenSSH's VerifyHostKeyDNS-enabled client (bsc#1237040).</li>
</ul>
<p>Other bugfixes:</p>
<ul>
<li>Fix usage of local accelerator cards via openssl-ibmca (bsc#1216474, bsc#1218871).</li>
<li>Add patches from upstream to change the default value of UpdateHostKeys to Yes (unless VerifyHostKeyDNS is enabled) (bsc#1222831).</li>
<li>Fix hostbased ssh login failing occasionally with "signature unverified: incorrect signature" by fixing a typo in patch (bsc#1221123).</li>
<li>For now we don't ship the ssh-keycat command, but we need the patch for the other SELinux infrastructure (bsc#1214788).</li>
<li>Attempts to mitigate instances of secrets lingering in memory after a session exits (bsc#1213004, bsc#1213008, bsc#1186673).</li>
</ul>
