CVE-2012-0854

Publication date 20 August 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

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.

from upstream, "Wrong pointer being used to write after recent audio API change."

doesn't look like it affects libav 0.7 and older, and ffmpeg 0.5
