Description

FFmpeg through 9.0.2 contains a division by zero vulnerability in ff_aom_parse_film_grain_sets() that fails to reject AFGS1 scaling points with repeated x values. Attackers can supply crafted HEVC or VVC files with zero-increment scaling points in T.35 SEI messages, causing generate_scaling() to divide by zero and crash the decoder.
