Description OSIDB Bzimport 2026-11-10 19:21:00 UTC 
FFmpeg through 9.0.2 contains a division by zero vulnerability in estimate_motion_b() in libavcodec/motion_est.c, caused by frame timestamp distances truncated to 16 bits. Attackers can supply input with timestamp gaps that are multiples of 65536, crashing MPEG-4 Part 2 or MPEG-1/2 B-frame encoding with SIGFPE.
