Debian Security Advisory DSA-5199-1 [email protected]

Package : xorg-server
CVE ID : CVE-2022-2319 CVE-2022-2320
Debian Bug : 1014903

Jan-Niklas Sohn discovered that multiple input validation failures in
the Xkb extension of the X.org X server 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+deb11u2.

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:
https://security-tracker.debian.org/tracker/xorg-server

these updates to your system and frequently asked questions can be
