The vc1_decode_frame function in libavcodec/vc1dec.c in Libav 12.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
