{"id":"CVE-2019-17185","details":"In FreeRADIUS 3.0.x before 3.0.20, the EAP-pwd module used a global OpenSSL BN_CTX instance to handle all handshakes. This mean multiple threads use the same BN_CTX instance concurrently, resulting in crashes when concurrent EAP-pwd handshakes are initiated. This can be abused by an adversary as a Denial-of-Service (DoS) attack.","modified":"2026-05-17T03:55:05.923193060Z","published":"2020-03-21T01:15:12.243Z","related":["SUSE-SU-2020:1018-1","SUSE-SU-2020:1020-1","SUSE-SU-2020:1023-1","SUSE-SU-2020:2391-1","openSUSE-SU-2020:0553-1","openSUSE-SU-2024:10767-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:opensuse:leap:15.1:*:*:*:*:*:*:*"],"source":"CPE_FIELD","extracted_events":[{"last_affected":"15.1"}],"vendor_product":"opensuse:leap"}]},"references":[{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00039.html"},{"type":"ADVISORY","url":"https://freeradius.org/security/"},{"type":"ADVISORY","url":"https://github.com/FreeRADIUS/freeradius-server/releases/tag/release_3_0_20"}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
