Description OSIDB Bzimport 2026-11-10 20:05:01 UTC

FFmpeg through 9.0.2 contains an integer overflow vulnerability in the pcm_rechunk bitstream filter that allows attackers to trigger division by zero via a crafted channel count. Attackers can supply a file declaring a huge channel count that is remuxed into MXF, GXF or DAUD, overflowing sample_size and crashing the application.
