CVE-2019-17185

HIGH

FreeRADIUS 3.0.0-3.0.19 - Denial of Service via Concurrent EAP-pwd Handshakes

Title source: llm

Description

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.
