Doc Text:
A flaw was found in FFmpeg. An attacker could exploit this flaw by supplying a specially crafted media file containing an oversized Advanced Audio Coding (AAC) packet during processing or remuxing operations. This causes an unchecked bit parsing failure that triggers a null pointer dereference, crashing the application and resulting in a Denial of Service (DoS).

Description OSIDB Bzimport 2026-11-10 20:07:35 UTC
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in aac_adtstoasc_filter() that allows attackers to crash applications via oversized ADTS AAC packets. Attackers can supply a crafted file with a packet over 256 MB, overflowing the bit count so init_get_bits() fails unchecked and get_bits() crashes during MP4, Matroska, FLV or LATM remuxing.
