A ~50-byte crafted FLAC file declaring ~100 million samples causes a multi-gigabyte memory allocation, leading to out-of-memory denial of service during 'decrypt --stego-extract'. The issue is fixed in 1.4.9; both the 1.4.x and 1.5.x lines are affected.","published":"2026-08-27T17:20:59.140","modified":"2026-08-27T17:20:59.140","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-wr9q-p3rj-vqq7"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-denial-of-service-via-streaminfo"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T17:20:59.140"}}
