Description

It was discovered that there was a memory corruption issue in libav (a multimedia player, server, encoder and transcoder) when parsing .mp4 files which could lead to crash or possibly execute arbitrary code.

For Debian 7 'Wheezy', this issue has been fixed in libav version 6:0.8.17-2+deb7u2.

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.
