Ubuntu 22.04 LTS / 24.04 LTS / 24.10 / 25.04 : X.Org X Server vulnerabilities (USN-7573-1)

medium Nessus Plugin ID 240160

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 24.10 / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7573-1 advisory.

Nils Emmerich discovered that the X.Org X Server incorrectly handled certain memory operations. An attacker could use these issues to cause the X Server to crash, leading to a denial of service, obtain sensitive information, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
