freeradius security update

CentOS Errata and Security Advisory CESA-2012:1326

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)

Red Hat would like to thank Timo Warns of PRESENSE Technologies GmbH for
reporting this issue.

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.
