More information:

Jan-Niklas Sohn discovered several vulnerabilities in X server extensions in the X.Org X server, which may result in privilege escalation if the X server is running privileged.

For the stable distribution (bullseye), these problems have been fixed in version 2:1.20.11-1+deb11u4.

We recommend that you upgrade your xorg-server packages.
