{"id":"CVE-2026-81692","summary":"openssl_encrypt before 1.4.9 Denial of Service via STREAMINFO","details":"openssl_encrypt (pip: openssl-encrypt) versions 1.4.8 and earlier fail to validate the 36-bit STREAMINFO total_samples field of FLAC files before using it to size an allocation (np.random.randint(size=(total_samples, channels))). 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.","aliases":["GHSA-wr9q-p3rj-vqq7"],"modified":"2026-09-02T03:30:49.608804151Z","published":"2026-08-27T14:50:56.894Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81692.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-789"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/81xxx/CVE-2026-81692.json"},{"type":"ADVISORY","url":"https://github.com/jahlives/openssl_encrypt/security/advisories/GHSA-wr9q-p3rj-vqq7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-81692"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openssl-encrypt-before-1.4.9-denial-of-service-via-streaminfo"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jahlives/openssl_encrypt","events":[{"introduced":"0"},{"fixed":"39b0a010cae90520f74b7194f61fedd43af04ef8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.4.9"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.2","v1.4.1rc2","v1.4.1rc1","v1.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-81692.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
