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.
