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, >=0.6.6 should be safe,\n- if you rely on `libloading`, you must upgrade to 0.8.0 _and_ use their latest DLL >=2.6.0. \n\nUsers handling untrusted video files should update immediately.","published":"2025-02-24T18:27:25Z","modified":"2025-10-28T06:29:23.180686Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"openh264-sys2","fixedVersion":"0.8.0"}],"fix":{"url":"https://github.com/cisco/openh264/pull/3818","label":"cisco/openh264#3818"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2025-10-28T06:29:23.180686Z"}}
