{"id":"JLSEC-2026-1188","summary":"FFmpeg versions from 0.5 up to, but not including, 9.0 contain a signed integer overflow...","details":"FFmpeg versions from 0.5 up to, but not including, 9.0 contain a signed integer overflow vulnerability in the DVB subtitle parser in `libavcodec/dvbsub_parser.c` that allows attackers to trigger a heap buffer overflow by supplying a crafted WTV file. The overflow causes the bounds-check guard expression to wrap to `INT_MIN`, bypassing the `PARSE_BUF_SIZE` comparison and invoking memcpy() with attacker-controlled data into a heap buffer, resulting in an out-of-bounds heap write and potential memory corruption or code execution.","modified":"2026-08-08T23:15:05.812629345Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-70628","GHSA-qw9h-2hhv-hpfr","EUVD-2026-54160"],"database_specific":{"license":"CC-BY-4.0","sources":[{"published":"2026-08-06T22:18:26.957Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-70628","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70628","database_specific":{"status":"Received"},"id":"CVE-2026-70628","imported":"2026-08-08T05:24:43.617Z","modified":"2026-08-07T18:17:21.783Z"},{"modified":"2026-08-07T18:31:42Z","published":"2026-08-07T00:31:21Z","url":"https://api.github.com/advisories/GHSA-qw9h-2hhv-hpfr","html_url":"https://github.com/advisories/GHSA-qw9h-2hhv-hpfr","id":"GHSA-qw9h-2hhv-hpfr","imported":"2026-08-08T05:25:33.259Z"},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-54160","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-54160","id":"EUVD-2026-54160","imported":"2026-08-08T05:24:17.774Z","modified":"2026-08-07T17:10:51Z","published":"2026-08-06T21:24:15Z"}]},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/02fc47e13f903768b75f7985a2706a6223ab4506"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/93f2a525ec6c7b467bae68322720d10188fc6e30"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/c6ec28b18cd1eb7d39e6163137367f2d1c62aa7c"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23897"},{"type":"WEB","url":"https://github.com/advisories/GHSA-qw9h-2hhv-hpfr"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70628"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-dvb-subtitle-parser-heap-buffer-overflow-via-wtv-file"}],"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-2026-1188.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-2026-1188.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-2026-1188.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"}]}
