There exists a NULL pointer dereference in ff_vc1_parse_frame_header_adv in vc1.c in Libav 12.3, which allows attackers to cause a denial-of-service through a crafted aac file.
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.
