Attackers can craft a truncated Sun Raster file so the uncleared temporary bitmap is expanded into PAL8 pixels, exposing stale heap contents such as allocator words in decoded output.","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/24877","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/sunrast.c#L188-L194","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/356a391bf57df2fb80fd61f2821c8c83d15ce180","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/66b6ca270b33fd74367d7d371f6de16ec664446e","tags":[]},{"url":"https://www.vulncheck.com/advisories/ffmpeg-0.10-through-9.0.2-uninitialized-memory-disclosure-via-sun-raster-decoder","tags":[]}],"exploitRefs":[{"url":"https://github.com/FFmpeg/FFmpeg","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/sunrast.c#L188-L194","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/356a391bf57df2fb80fd61f2821c8c83d15ce180","tags":[]},{"url":"https://github.com/FFmpeg/FFmpeg/commit/66b6ca270b33fd74367d7d371f6de16ec664446e","tags":[]}],"hasPoc":true,"ai":null}
