Several vulnerabilities have been discovered in FFmpeg, a multimedia player, server and encoder. Multiple input validations in the decoders/ demuxers for Westwood Studios VQA, Apple MJPEG-B, Theora, Matroska, Vorbis, Sony ATRAC3, DV, NSV, files could lead to the execution of arbitrary code.

These issues were discovered by Aki Helin, Mateusz Jurczyk, Gynvael Coldwind, and Michael Niedermayer.
