<p>An update that solves two vulnerabilities and has 12 fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for openssh fixes the following issues:</p>
<ul>
<li>CVE-2025-26465: Fixed MitM attack against OpenSSH's VerifyHostKeyDNS-enabled client (bsc#1237040).</li>
<li>CVE-2025-26466: Fixed DoS attack against OpenSSH's client and server (bsc#1237041).</li>
</ul>
<p>Other bugfixes:</p>
<ul>
<li>Fix ssh client segfault with GSSAPIKeyExchange=yes in ssh_kex2 due to gssapi proposal not being correctly initialized (bsc#1236826). </li>
<li>Add #include <stdlib.h> in some files added by the ldap patch to fix build with gcc14 (bsc#1225904).</li>
<li>Added missing struct initializer, added missing parameter (bsc#1222840).</li>
<li>Remove OPENSSL_HAVE_EVPGCM-ifdef, which is no longer supported by upstream (bsc#1221928). </li>
<li>Use %config(noreplace) for sshd_config. In any case, it's recommended to drop a file in sshd_config.d instead of editing sshd_config (bsc#1221063).</li>
<li>Add a patch to fix a regression introduced in 9.6 that makes X11 forwarding very slow (bsc#1229449).</li>
<li>Drop keycat binary that is not supported, except of the code that is used by other SELinux patches (bsc#1229072).</li>
<li>Fix RFC4256 implementation that keyboard-interactive authentication method can send instructions and sshd shows them to users (bsc#1229010).</li>
<li>Add attempts to mitigate instances of secrets lingering in memory after a session exits (bsc#1186673, bsc#1213004, bsc#1213008).</li>
<li>Remove empty line at the end of sshd-sle.pamd (bsc#1227456)</li>
</ul>
