Doc Text:
A flaw was found in FFmpeg. An attacker could exploit an out-of-bounds read vulnerability in the DVD audio encoder to cause a Denial of Service (DoS) by crashing the transcoding process. By tricking a user or service into processing a specially crafted audio file with an irregular final frame length, the encoder miscalculates frame boundaries and attempts to read memory beyond allocated buffers.

Description OSIDB Bzimport 2026-11-10 13:03:44 UTC
FFmpeg through 9.0.2 contains an out-of-bounds read vulnerability in pcm_dvd_encode_frame() in libavcodec/pcm-dvdenc.c when a 24-bit final frame holds fewer samples than one block. Attackers can supply 24-bit 48 or 96 kHz audio whose length leaves a short final frame, causing the loop counter to wrap and crash the transcoding process.
