{"id":"CVE-2018-12384","details":"When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS 1.3.","modified":"2026-04-16T01:37:51.469139562Z","published":"2019-04-29T15:29:00.247Z","related":["SUSE-SU-2018:4235-1","SUSE-SU-2018:4236-1","SUSE-SU-2018:4236-2","openSUSE-SU-2024:11058-1"],"references":[{"type":"ADVISORY","url":"https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html"},{"type":"REPORT","url":"https://bugzilla.mozilla.org/show_bug.cgi?id=CVE-2018-12384"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2018-12384.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"3.39"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
