FFmpeg through 9.0.2 contains an uncontrolled memory allocation vulnerability in the Interplay ACM decoder that allows attackers to exhaust memory via an attacker-controlled block size. Attackers can supply a crafted ACM file with maximum level and row count in extradata, making decode_init() allocate nearly a gigabyte and deny service.
