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.

For the detailed security status of xorg-server please refer to its security tracker page at:
