{"id":"JLSEC-2026-1192","summary":"FFmpeg versions from 4.4 up to, but not including, 9.0 contain an out-of-bounds heap write...","details":"FFmpeg versions from 4.4 up to, but not including, 9.0 contain an out-of-bounds heap write vulnerability in the native GoPro CineForm HD (CFHD) decoder that allows remote attackers to corrupt heap memory by supplying a crafted AVI file during stream probing. The `cfhd_decode()` function fails to enforce the non-Bayer logical output-width invariant in the transform-type-2 reconstruction path, causing `horiz_filter_clip()` to write oversized 16-bit sample rows far beyond the allocated output frame buffer, which can be escalated to arbitrary code execution via overwrite of a live cleanup callback pointer.","modified":"2026-08-08T23:15:04.272634263Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-70632","GHSA-q24x-99v6-6hxc","EUVD-2026-54166"],"database_specific":{"sources":[{"published":"2026-08-06T22:18:27.567Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-70632","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70632","database_specific":{"status":"Received"},"id":"CVE-2026-70632","imported":"2026-08-08T05:24:19.300Z","modified":"2026-08-07T18:17:22.307Z"},{"imported":"2026-08-08T05:25:39.276Z","modified":"2026-08-07T18:31:42Z","published":"2026-08-07T00:31:21Z","url":"https://api.github.com/advisories/GHSA-q24x-99v6-6hxc","html_url":"https://github.com/advisories/GHSA-q24x-99v6-6hxc","id":"GHSA-q24x-99v6-6hxc"},{"id":"EUVD-2026-54166","imported":"2026-08-08T05:24:17.710Z","modified":"2026-08-07T17:20:24Z","published":"2026-08-06T21:26:17Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-54166","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-54166"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/1006a2151236f9235bf02822f263b3fb0532111e"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/16b2049d4d5222db6cd7c031409058571c94f6a9"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/db05df9d135fb56a4babb836d5e9f5c1d984e087"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23898"},{"type":"WEB","url":"https://github.com/advisories/GHSA-q24x-99v6-6hxc"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70632"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-heap-out-of-bounds-write-in-cfhd-decoder-via-avi-demuxing"}],"affected":[{"package":{"name":"FFMPEG_jll","ecosystem":"Julia","purl":"pkg:julia/FFMPEG_jll?uuid=b22a6f82-2f65-5046-a5b2-351ab43fb4e5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.4.0+0"},{"fixed":"9.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1192.json"}},{"package":{"name":"FFMPEG_nogpl_jll","ecosystem":"Julia","purl":"pkg:julia/FFMPEG_nogpl_jll?uuid=a6892c6b-5768-548c-b024-ff8dabf482c5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1192.json"}},{"package":{"name":"FFplay_jll","ecosystem":"Julia","purl":"pkg:julia/FFplay_jll?uuid=c4dce911-e170-5107-8314-c7bdc6785395"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.4.4+0"},{"fixed":"9.0.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1192.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/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"}]}
