When `config_input()` allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, `filter_frame()` performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening.","modified":"2026-08-07T13:43:39.758413677Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-65705","EUVD-2026-48372","GHSA-gf7r-r5xq-r3hm"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-07-23T20:17:22.120Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-65705","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65705","database_specific":{"status":"Analyzed"},"id":"CVE-2026-65705","imported":"2026-08-07T05:41:14.663Z","modified":"2026-08-07T00:20:32.650Z"},{"modified":"2026-07-23T21:31:09Z","published":"2026-07-23T21:31:02Z","url":"https://api.github.com/advisories/GHSA-gf7r-r5xq-r3hm","html_url":"https://github.com/advisories/GHSA-gf7r-r5xq-r3hm","id":"GHSA-gf7r-r5xq-r3hm","imported":"2026-08-07T05:41:16.863Z"},{"html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-48372","id":"EUVD-2026-48372","imported":"2026-08-07T05:41:15.493Z","modified":"2026-07-28T01:06:13Z","published":"2026-07-23T19:00:36Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-48372"}]},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/f186c50cf53aec20e9a29059cb22ca3f2d59201c"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23780"},{"type":"WEB","url":"https://github.com/advisories/GHSA-gf7r-r5xq-r3hm"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65705"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-vf-floodfill-out-of-bounds-write-via-filter-frame"}],"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-2026-1180.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-2026-1180.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-2026-1180.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: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"}]}
