FFmpeg through 9.0.2 contains a deadlock vulnerability in mimic_decode_frame() in libavcodec/mimic.c that fails to report frame progress when init_get_bits8() fails. Attackers can supply a crafted file with an oversized Mimic intra frame followed by inter frames to hang frame-threaded decoding indefinitely.
