<p>The Security SIG repositories provide extra security-related packages and security-hardened override packages (replacing those from the main distribution) for Rocky Linux and other Enterprise Linux (EL) distributions.</p>
<h2 id="responsibilities">Responsibilities<a class="headerlink" href="#responsibilities" title="Permanent link">&para;</a></h2>
<p>Developing and maintaining various security related packages that are not in upstream EL. Identifying, developing, and maintaining security hardening changes relative to upstream EL packages. Occasionally including/backporting additional security fixes that are not yet in upstream EL packages. Contributing to the respective upstreams where practical.</p>

<li>glibc (adds many security-hardening changes originating from Owl and ALT Linux on top of EL package)</li>
<li>openssh (fewer shared libraries exposed in sshd processes while otherwise fully matching EL package's functionality)</li>
</ul>
<p>The changes are described in more detail in the package changelogs.
More packages/changes are planned, including override packages also for EL8.</p>
<h4 id="known-effective-vulnerability-mitigations-and-fixes">Known-effective vulnerability mitigations and fixes<a class="headerlink" href="#known-effective-vulnerability-mitigations-and-fixes" title="Permanent link">&para;</a></h4>
<p><code>glibc-2.34-60.el9_2.security.0.2</code> (specifically the <code>.0.2</code> version!) includes mitigations sufficient to avoid security exposure of <a href="https://www.openwall.com/lists/oss-security/2023/10/03/2">CVE-2023-4911</a> and a backport of upstream glibc fix of <a href="https://www.openwall.com/lists/oss-security/2023/09/25/1">CVE-2023-4527</a> that was not yet in upstream EL.</p>
<p>The inclusion of additional security fixes will be "reverted" if and when those get included in upstream EL packages that we rebase our changes on.</p>
<h2 id="source-code">Source code<a class="headerlink" href="#source-code" title="Permanent link">&para;</a></h2>
<p>Just like for other Rocky Linux SIGs, the source trees for Security SIG packages are maintained in <a href="https://git.rockylinux.org/sig/security/src">per-package git repositories</a>. Each repository contains branches <code>r8</code> and/or <code>r9</code> corresponding to target EL version.</p>

<p>If anyone else wants to join this effort - in any capacity including development, maintenance, testing, documentation, user support, spreading the word, or something else - please join the Mattermost channel below and let us know!</p>
<p>We also welcome well-reasoned suggestions/feedback/preferences on direction we should take (e.g., only making changes on top of EL's vs. offering newer upstream versions), what else to package, and what other changes to include.</p>
