Package : xorg-server
Version : 2:1.20.4-1+deb10u5
CVE ID : CVE-2022-2319 CVE-2022-2320

Jan-Niklas Sohn discovered two out of bound memory writes in X.Org Server's
ProcXkbSetGeometry and ProcXkbSetDeviceInfo Xkb extensions. These issues
could be exploited by an attacker to cause denial of service, privilege
escalation or arbitrary code execution.

For Debian 10 buster, these problems have been fixed in version
2:1.20.4-1+deb10u5.

We recommend that you upgrade your xorg-server packages.
