{"id":"JLSEC-2026-1175","summary":"FFmpeg versions 0.7.1 through 8.1.2 contain an out-of-bounds read vulnerability in the S/PDIF...","details":"FFmpeg versions 0.7.1 through 8.1.2 contain an out-of-bounds read vulnerability in the S/PDIF muxer that allows attackers to access memory beyond buffer boundaries by supplying a crafted DTS stream with a `core_size` value larger than the actual packet length. Attackers can exploit the missing bounds check in the `spdif_header_dts4` function by providing a malicious DTS-HD audio stream during S/PDIF re-muxing to trigger unauthorized memory reads beyond the packet buffer.","modified":"2026-08-08T23:15:04.277047669Z","published":"2026-08-07T13:27:45.313Z","upstream":["CVE-2026-64833","GHSA-34g6-m4cp-w5c9","EUVD-2026-47757"],"database_specific":{"sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-64833","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64833","database_specific":{"status":"Analyzed"},"id":"CVE-2026-64833","imported":"2026-08-08T05:24:16.059Z","modified":"2026-07-28T17:01:39.307Z","published":"2026-07-22T18:17:05.627Z"},{"html_url":"https://github.com/advisories/GHSA-34g6-m4cp-w5c9","id":"GHSA-34g6-m4cp-w5c9","imported":"2026-08-08T05:25:38.718Z","modified":"2026-07-22T18:32:47Z","published":"2026-07-22T18:32:40Z","url":"https://api.github.com/advisories/GHSA-34g6-m4cp-w5c9"},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-47757","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-47757","id":"EUVD-2026-47757","imported":"2026-08-08T05:24:18.691Z","modified":"2026-07-28T01:06:04Z","published":"2026-07-22T17:03:20Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/6f80e2765492700622596af720534cef33dd31b4"},{"type":"WEB","url":"https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23661"},{"type":"WEB","url":"https://github.com/advisories/GHSA-34g6-m4cp-w5c9"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64833"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/ffmpeg-out-of-bounds-read-via-s-pdif-muxer-spdifenc-c"}],"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-2026-1175.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-2026-1175.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-2026-1175.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:L/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/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"}]}
