Summary
FFmpeg versions up to 9.0.2 have a NULL pointer dereference in the EA TQI video decoder that a local attacker can trigger by getting a user to open a crafted EA file, causing the process to crash and denying service. No login is needed, but the victim must take an action such as opening the file.

Read the original 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.
