Debian DLA-671-1 : libxvmc security update

critical Nessus Plugin ID 94145

Synopsis

The remote Debian host is missing a security update.

Description

CVE-2016-7953 If an empty string is received from an x-server, do not underrun the buffer by accessing 'rep.nameLen - 1' unconditionally, which could end up being -1.

For Debian 7 'Wheezy', these problems have been fixed in version 2:1.0.7-1+deb7u3.

We recommend that you upgrade your libxvmc 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 libxvmc-dev, libxvmc1, and libxvmc1-dbg packages.
