<p>Multiple vulnerabilities have been discovered in X.Org X Server and XWayland. Please review the CVE identifiers referenced below for details.</p>
</description>
<impact type="normal">
<p>The X server can be crashed by a malicious client, or potentially be compromised for remote code execution in environments with X11 forwarding.</p>
