Package        : xorg-server
Version        : 2:1.20.11-1+deb11u14
CVE ID         : CVE-2024-9632


Jan-Niklas Sohn working with Trend Micro Zero Day Initiative found an 
issue in the X server and Xwayland implementations published by X.Org.
CVE-2024-9632 can be triggered by providing a modified bitmap to the X.Org 
server. This may lead to local privilege escalation if the server is run 
as root or remote code execution (e.g. x11 over ssh).


For Debian 11 bullseye, this problem has been fixed in version
2:1.20.11-1+deb11u14.

We recommend that you upgrade your xorg-server packages.
