FFmpeg through 9.0.2 contains an uninitialized memory vulnerability in the VQA video decoder in libavcodec/vqavideo.c that allows attackers to disclose heap memory via a crafted VQA file. Attackers can supply a Westwood VQA file omitting or truncating the CBF0/CBFZ codebook chunk, causing vqa_decode_frame() to render frames from leftover heap bytes visible in decoded output.
