CVE-2013-7020 — Improper Restriction of Operations within the Bounds of a Memory Buffer in Ffmpeg

The read_header function in libavcodec/ffv1dec.c in FFmpeg before 2.1 does not properly enforce certain bit-count and colorspace constraints, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted FFV1 data.
