3. Description:

FreeRADIUS is a high-performance and highly configurable free Remote
Authentication Dial In User Service (RADIUS) server, designed to allow
centralized authentication and authorization for a network.

Security Fix(es):

* An authentication bypass flaw was found in the way the EAP module in
FreeRADIUS handled TLS session resumption. A remote unauthenticated
attacker could potentially use this flaw to bypass the inner authentication
check in FreeRADIUS by resuming an older unauthenticated TLS session.
