Description:
 The dpcm_decode_frame function in libavcodec/dpcm.c in FFmpeg before 0.9.1
 does not use the proper pointer after an audio API change, which allows
 remote attackers to cause a denial of service (application crash) via
 unspecified vectors, which triggers a heap-based buffer overflow.
Ubuntu-Description:
Notes:
 jdstrand> from upstream, "Wrong pointer being used to write after recent audio API change."
 mdeslaur> doesn't look like it affects libav 0.7 and older, and ffmpeg 0.5
