Description

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.
