Doc Text:
A flaw was found in FFmpeg that can lead to a Denial of Service (DoS). By tricking a user into processing a specially crafted Monkey's Audio (APE) file, an attacker can trigger excessive memory allocation due to missing validation on legacy audio frame sizes. This can exhaust available system memory and cause the application to crash.

Description OSIDB Bzimport 2026-11-10 13:01:26 UTC
FFmpeg through 9.0.2 contains a memory exhaustion vulnerability in ape_decode_frame() in libavcodec/apedec.c that fails to enforce the 73728-sample limit for legacy APE frames. Attackers can supply a crafted legacy Monkey's Audio file declaring an enormous nblocks value to force gigabyte-scale allocations and cause denial of service.
