Kerentanan Improper Synchronization pada freeradius, opensuse leap. Skor CVSS 3.1 7.5 (High) menurut NVD.

Deskripsi (NVD)

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.
