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. (CVE-2017-9148)
