Ubuntu 14.04 LTS : X.Org X server vulnerabilities (USN-2436-1)

high Nessus Plugin ID 79852

Synopsis

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

Description

Ilja van Sprundel discovered a multitude of security issues in the X.Org X server. An attacker able to connect to an X server, either locally or remotely, could use these issues to cause the X server to crash or execute arbitrary code resulting in possible privilege escalation.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
