Red Hat Security Advisory 2012-1326-01 - FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service server, designed to allow centralized authentication and authorization for a network. A buffer overflow flaw was discovered in the way radiusd handled the expiration date field in X.509 client certificates. A remote attacker could possibly use this flaw to crash radiusd if it were configured to use the certificate or TLS tunnelled authentication methods.
