Debian DLA-686-1 : libxtst security update

critical Nessus Plugin ID 94300

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Tobias Stoeckmann from the OpenBSD project discovered the following vulnerability in libXtst, the X Record extension :

Insufficient validation of data from the X server can cause out of boundary memory access or endless loops (Denial of Service).

For Debian 7 'Wheezy', these problems have been fixed in version 2:1.2.1-1+deb7u2.

We recommend that you upgrade your libxtst 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.
