Description
FFmpeg through 9.0.2 contains an uninitialized memory vulnerability in the DXA decoder in libavcodec/dxa.c that allows attackers to disclose heap memory via crafted DXA files. Attackers can supply a DXA video with a type 4 frame that copies the uninitialized decomp_buf buffer into output pictures, exposing leftover heap contents in decoded frames.
