Attackers can craft a PCX image whose RLE data ends early, causing pcx_decode_frame() to copy uninitialized av_malloc() buffer contents into visible decoded pixels.","cvssScore":5.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cwes":["CWE-908"],"vendors":[],"products":[],"references":[{"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24868","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/pcx.c#L45-L59","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ecd5dfc308a164757e7f25b1afefd8db21b43cf9","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-2.1-through-9.0.2-uninitialized-memory-leak-via-pcx-decoder","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/pcx.c#L45-L59","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/ecd5dfc308a164757e7f25b1afefd8db21b43cf9","tags":[]}],"hasPoc":true,"ai":null}
