Attackers can supply a crafted 15/16 bpp FLIC/FLX file with an FLI_BRUN chunk whose non-terminating byte-swap loop writes packet-derived data past the frame buffer, crashing the process.","epss":{"date":"2026-11-13","percentile":0.02646,"score":0.00129},"exploits":[],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":7,"severity":"high","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.3,"severity":"high","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/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":7,"severity":"high","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1794621599500,"publishedAt":1794251466838,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking"],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24901"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/ee30fb98c0d4e97abbd5e371d2a3a926e92bec70"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/c0d308a9a616f4abcc4e0a4d86f7de92ecdef9f6"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/FFmpeg/FFmpeg/commit/eb47d7bb6cf13042c6ab14e22fc0c0c3a6e51e12"},{"source":"CNA: VulnCheck","tags":["technical-description"],"url":"https://github.com/FFmpeg/FFmpeg/blob/n9.0.2/libavcodec/flicvideo.c#L883"},{"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-through-9.0.2-flic-decoder-out-of-bounds-write-via-fli-brun-byte-swap"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/24901"},{"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/flicvideo.c#L883"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/commit/c0d308a9a616f4abcc4e0a4d86f7de92ecdef9f6"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/commit/eb47d7bb6cf13042c6ab14e22fc0c0c3a6e51e12"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/FFmpeg/FFmpeg/commit/ee30fb98c0d4e97abbd5e371d2a3a926e92bec70"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/ffmpeg-through-9.0.2-flic-decoder-out-of-bounds-write-via-fli-brun-byte-swap"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
