CVE-2012-0854: Buffer Overflow

First published: Mon Aug 20 2012(Updated: )

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.
