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.","cvssScore":3.3,"cvssSeverity":"LOW","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","cwes":["CWE-908"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24463","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/dxa.c#L341","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a6e5d5ff993a525933d8d8f29071eb6c74b0436a","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-heap-memory-disclosure-via-dxa-decoder-uninitialized-buffer","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/dxa.c#L341","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/a6e5d5ff993a525933d8d8f29071eb6c74b0436a","tags":[]}],"hasPoc":true,"ai":null}
