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 Debian 10 buster, these problems have been fixed in version 2:1.20.4-1+deb10u7.

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:
