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.","epss":{"date":"2026-11-02","percentile":0.02087,"score":0.00124},"exploits":[],"kev":null,"metrics":[{"score":6.8,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},{"score":5.5,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},{"score":6.8,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":5.5,"severity":"medium","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"}],"modifiedAt":1793630404609,"publishedAt":1793494630732,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24877"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/356a391bf57df2fb80fd61f2821c8c83d15ce180"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/66b6ca270b33fd74367d7d371f6de16ec664446e"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/sunrast.c#L188-L194"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://github.com/FFmpeg/FFmpeg"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/ffmpeg-0.10-through-9.0.2-uninitialized-memory-disclosure-via-sun-raster-decoder"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24877"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/sunrast.c#L188-L194"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/commit/356a391bf57df2fb80fd61f2821c8c83d15ce180"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/commit/66b6ca270b33fd74367d7d371f6de16ec664446e"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/ffmpeg-0.10-through-9.0.2-uninitialized-memory-disclosure-via-sun-raster-decoder"}],"remediation":[],"revision":"69068388de264b2aaf110037707da0a48f3cbb3b4dfccc04dda8e4a4c83e154b","sources":[{"modifiedAt":1793630404609,"name":"CNA: VulnCheck","retrievedAt":1793632114856,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120245"},{"modifiedAt":1793495837960,"name":"NVD","retrievedAt":1793578559220,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-120245"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793632117281,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-120245"}],"ssvc":{"assessedAt":1793630393499,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"FFmpeg 0.10 through 9.0.2 Uninitialized Memory Disclosure via Sun Raster Decoder","updatedAt":1793632117281}
