{"id":"JLSEC-2026-1182","summary":"FFmpeg through 8.1.2, fixed in commit 5d7112c, contains a heap out-of-bounds write vulnerability...","details":"FFmpeg through 8.1.2, fixed in commit 5d7112c, contains a heap out-of-bounds write vulnerability in the `vf_hqdn3d` filter that allows attackers to corrupt heap memory by supplying a crafted video whose frame resolution increases between frames when filtergraph reinitialization is disabled via the -reinit_filter 0 option. Attackers can provide a malicious video input where `vf_hqdn3d.config_input()` allocates undersized per-plane line-history buffers based on the initial frame width, and subsequent larger frames cause `denoise_spatial()` to write beyond the allocation boundary, resulting in heap memory corruption.","modified":"2026-08-07T13:43:41.062912338Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-66036","EUVD-2026-48738","GHSA-575m-jfmw-q76c"],"database_specific":{"license":"CC-BY-4.0","sources":[{"database_specific":{"status":"Analyzed"},"id":"CVE-2026-66036","imported":"2026-08-07T05:41:14.706Z","modified":"2026-08-07T01:05:17.870Z","published":"2026-07-24T20:18:20.433Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-66036","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66036"},{"imported":"2026-08-07T05:42:36.715Z","modified":"2026-07-24T21:32:28Z","published":"2026-07-24T21:32:22Z","url":"https://api.github.com/advisories/GHSA-575m-jfmw-q76c","html_url":"https://github.com/advisories/GHSA-575m-jfmw-q76c","id":"GHSA-575m-jfmw-q76c"},{"imported":"2026-08-07T05:41:15.317Z","modified":"2026-07-29T03:55:35Z","published":"2026-07-24T19:34:16Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-48738","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-48738","id":"EUVD-2026-48738"}]},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/5d7112c60e6f0f0742ce47d448e6da0718a70f4c"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23783"},{"type":"WEB","url":"https://github.com/advisories/GHSA-575m-jfmw-q76c"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-66036"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-heap-out-of-bounds-write-in-vf-hqdn3d-filter"}],"affected":[{"package":{"name":"FFMPEG_jll","ecosystem":"Julia","purl":"pkg:julia/FFMPEG_jll?uuid=b22a6f82-2f65-5046-a5b2-351ab43fb4e5"},"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-2026-1182.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-2026-1182.json"}},{"package":{"name":"FFplay_jll","ecosystem":"Julia","purl":"pkg:julia/FFplay_jll?uuid=c4dce911-e170-5107-8314-c7bdc6785395"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1182.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/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"}]}
