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.
