{"id":"JLSEC-2026-1178","summary":"FFmpeg versions 2.7 through 8.1.2 contain an out-of-bounds write vulnerability in the TDSC video...","details":"FFmpeg versions 2.7 through 8.1.2 contain an out-of-bounds write vulnerability in the TDSC video decoder that allows remote attackers to cause heap corruption by supplying a crafted AVI file that changes frame dimensions across TDSF frames. The `tdsc_parse_tdsf()` function fails to unreference the existing reference frame before calling `av_frame_get_buffer()`, causing `tdsc_blit()` and `tdsc_yuv2rgb()` to write attacker-controlled pixel data beyond the end of the undersized reference frame buffer, resulting in a process crash and potential code execution.","modified":"2026-08-08T23:15:04.306964422Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-65703","GHSA-x3xw-4qcq-c6mr","EUVD-2026-48370"],"database_specific":{"sources":[{"published":"2026-07-23T20:17:21.803Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-65703","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65703","database_specific":{"status":"Analyzed"},"id":"CVE-2026-65703","imported":"2026-08-08T05:24:16.116Z","modified":"2026-08-07T00:19:03.283Z"},{"published":"2026-07-23T21:31:02Z","url":"https://api.github.com/advisories/GHSA-x3xw-4qcq-c6mr","html_url":"https://github.com/advisories/GHSA-x3xw-4qcq-c6mr","id":"GHSA-x3xw-4qcq-c6mr","imported":"2026-08-08T05:25:08.210Z","modified":"2026-07-23T21:31:09Z"},{"imported":"2026-08-08T05:24:18.548Z","modified":"2026-07-28T01:06:11Z","published":"2026-07-23T18:52:19Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-48370","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-48370","id":"EUVD-2026-48370"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/fd3ee52fab34d98a95b787d0b5ff45685766200c"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23773"},{"type":"WEB","url":"https://github.com/advisories/GHSA-x3xw-4qcq-c6mr"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-65703"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-out-of-bounds-write-in-tdsc-video-decoder"}],"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-2026-1178.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-2026-1178.json"}},{"package":{"name":"FFplay_jll","ecosystem":"Julia","purl":"pkg:julia/FFplay_jll?uuid=c4dce911-e170-5107-8314-c7bdc6785395"},"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-2026-1178.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"}]}
