Debian DLA-1186-1 : xorg-server security update

critical Nessus Plugin ID 104745

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been discovered in the X.Org X server. An attacker who's able to connect to an X server could cause a denial of service or potentially the execution of arbitrary code.

For Debian 7 'Wheezy', these problems have been fixed in version 2:1.12.4-6+deb7u8.

We recommend that you upgrade your xorg-server packages.

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

Solution

Upgrade the affected packages.
