Description
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.
