Debian DLA-791-1 : libav security update

medium Nessus Plugin ID 96635

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Multiple integer overflows have been discovered in libav 11.8 and earlier, allowing remote attackers to cause a crash via a crafted MP3 file.

For Debian 7 'Wheezy', these problems have been fixed in version 6:0.8.20-0+deb7u1.

We recommend that you upgrade your libav 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.
