For users relying on Cisco's pre-compiled DLL, we also published 0.8.0, which is compatible with their latest fixed DLL version  2.6.0. \n\nIn other words:\n- if you rely on our `source` feature only, \u003e=0.6.6 should be safe,\n- if you rely on `libloading`, you must upgrade to 0.8.0 _and_ use their latest DLL \u003e=2.6.0. \n\nUsers handling untrusted video files should update immediately.","aliases":["RUSTSEC-2025-0008"],"modified":"2025-10-28T06:29:23.180686Z","published":"2025-02-24T18:27:25Z","database_specific":{"github_reviewed_at":"2025-02-24T18:27:25Z","nvd_published_at":null,"cwe_ids":["CWE-122","CWE-1395"],"severity":"HIGH","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27091"},{"type":"WEB","url":"https://github.com/cisco/openh264/pull/3818"},{"type":"WEB","url":"https://github.com/ralfbiedert/openh264-rs/commit/3a822fff0b4c9a984622ca2b179fe8898ac54b14"},{"type":"PACKAGE","url":"https://github.com/ralfbiedert/openh264-rs"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2025-0008.html"}],"affected":[{"package":{"name":"openh264-sys2","ecosystem":"crates.io","purl":"pkg:cargo/openh264-sys2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/02/GHSA-5pmw-9j92-3c4c/GHSA-5pmw-9j92-3c4c.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
