Bundled version of libav in gstreamer-ffmpeg contains a number of vulnerabilities.

Several vulnerabilities have been discovered in FFmpeg, a multimedia player, server and encoder. Multiple input validations in the decoders/demuxers for Shorten, Chinese AVS video, VP5, VP6, AVI, AVS and MPEG-1/2 files could lead to the execution of arbitrary code.

Most of these issues were discovered by Mateusz Jurczyk and Gynvael Coldwind.

It was discovered that FFmpeg incorrectly handled certain malformed media files. If a user were tricked into opening a crafted media file, an attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.

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