FKIE_CVE-2012-0854

Vulnerability from fkie_nvd - Published: 2012-08-20 19:55 - Updated: 2026-06-16 23:38
Severity
Summary
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.
