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.

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 (such as EAP-TLS, EAP-TTLS, and PEAP). (CVE-2012-3547)

Users of FreeRADIUS are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, radiusd will be restarted automatically.
