Description:
 The avcodec_decode_audio4 function in utils.c in libavcodec in FFmpeg
 before 1.1.3 does not verify the decoding state before proceeding with
 certain skip operations, which allows remote attackers to cause a denial of
 service (out-of-bounds array access and application crash) or possibly have
 unspecified other impact via crafted audio data.
Ubuntu-Description:

 mdeslaur> ffmpeg-extra in multiverse needs to have matching version
 mdeslaur> libav-extra is built with tarball produced by libav package
 jdstrand> avcodec_decode_audio4() does not exist in ffmpeg in Ubuntu 10.04 LTS
  or libav in Ubuntu 11.10
