FFmpeg through 9.0.2 contains a NULL pointer dereference vulnerability in tgv_decode_inter() in libavcodec/eatgv.c that ignores init_get_bits() failure on oversized packets. Attackers can supply a crafted EA file with a kVGT frame followed by an fVGT inter frame with a 2^28-byte compressed block section, crashing the process for denial of service.
