Description
FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in tqi_decode_frame() in libavcodec/eatqi.c, which ignores init_get_bits() failure after an integer overflow. Attackers can supply a crafted EA file with a pIQT chunk carrying a 2^28-byte payload to crash the process, causing denial of service.
