USN-5740-1: X.Org X Server vulnerabilities
23 November 2022
Several security issues were fixed in X.Org X Server.
It was discovered that X.Org X Server incorrectly handled certain inputs.
An attacker could use these issues to cause the server to crash, resulting
in a denial of service, or possibly execute arbitrary code.
The problem can be corrected by updating your system to the following package versions:
- xwayland - 2:1.18.4-0ubuntu0.12+esm4
- xserver-xorg-core - 2:1.18.4-0ubuntu0.12+esm4
- xserver-xorg-core-hwe-16.04 - 2:1.19.6-1ubuntu4.1~16.04.6+esm3
- xserver-xorg-core - 2:1.15.1-0ubuntu2.11+esm6
After a standard system update you need to reboot your computer to make
all the necessary changes.
