Attackers can supply a crafted AVI with a CSCD stream whose LZO or zlib frames decompress to fewer bytes than the frame size, recovering heap contents from the decoded or re-encoded output.","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/25716","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/cscd.c#L152","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/e58c4eb98f0f3c0523089fb9d037eedfcbd204d9","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-6.1-through-9.0.2-information-disclosure-via-camstudio-decoder-cscd-c","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/cscd.c#L152","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/e58c4eb98f0f3c0523089fb9d037eedfcbd204d9","tags":[]}],"hasPoc":true,"ai":null}
