Description:
 Unspecified vulnerability in the ac3_decode_frame function in
 libavcodec/ac3dec.c in FFmpeg before 0.11 and Libav 0.8.x before 0.8.4 has
 unknown impact and attack vectors, related to the "number of output
 channels" and "out of array writes."
Ubuntu-Description:
Notes:
 mdeslaur> ffmpeg-extra in multiverse needs to have matching version
 mdeslaur> libav-extra is built with tarball produced by libav package
 mdeslaur> cannot locate equivalent libav patch, even though 0.8.4
 mdeslaur> is supposed to fix it.
 mdeslaur> libav 0.8.5 also says it fixes it, but still cannot locate
 mdeslaur> patch
 jdstrand> looking at the logic in the videolan patch and the code in ffmpeg,
  this may not affect the version of ffmpeg in Ubuntu 10.04 LTS
