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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.10
Ubuntu 22.04
Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
