Updated freeradius packages that fix a security issue are now available for Red Hat Enterprise Linux 5.
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
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.
An input validation flaw was discovered in the way FreeRADIUS decoded specific RADIUS attributes from RADIUS packets. A remote attacker could use this flaw to crash the RADIUS daemon (radiusd) via a specially crafted RADIUS packet. (CVE-2009-3111)
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.
