Doc Text:
A flaw was found in the FFmpeg Bink video decoder. An attacker can exploit this vulnerability by tricking a user into processing a specially crafted Bink video file with an excessively large frame, causing an internal bit count overflow and a subsequent null pointer dereference. This issue causes the application to crash, resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-10 20:17:08 UTC
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in the Bink video decoder because decode_frame() in libavcodec/bink.c ignores init_get_bits() failure. Attackers can supply a crafted Bink file with a frame of about 2^28 bytes, overflowing the bit count and crashing the process for denial of service.
