CVE-2019-17185 (GCVE-0-2019-17185)

Vulnerability from cvelistv5 – Published: 2020-03-21 00:13 – Updated: 2024-08-05 01:33

Summary

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.

Severity

No CVSS data available.
