LibAVCodec AMV Out of Array Write

27/04/2011

Dominic Chell of NGS Secure has discovered a high risk vulnerability in LibAVCodec. Opening a malformed AMV file can 
result in an out of array write and potentially arbitrary code execution when using this library. Whilst the 
vulnerability may affect multiple applications that use this library, it was only tested on VLC media player.

Versions affected include:
VLC media player 1.1.9 and earlier releases.

This issue is addressed in the latest release of FFMpeg, which can be found at:

NGS Secure is going to withhold details of this flaw for three months.
