CentOS 3 / 4 / 5 : freeradius (CESA-2007:0338)

medium Nessus Plugin ID 25204

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated freeradius packages that fix a memory leak flaw are now available for Red Hat Enterprise Linux 3, 4, and 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 RADIUS server designed to allow centralized authentication and authorization for a network.

A memory leak flaw was found in the way FreeRADIUS parses certain authentication requests. A remote attacker could send a specially crafted authentication request which could cause FreeRADIUS to leak a small amount of memory. If enough of these requests are sent, the FreeRADIUS daemon would consume a vast quantity of system memory leading to a possible denial of service. (CVE-2007-2028)

Users of FreeRADIUS should update to these erratum packages, which contain a backported patch to correct this issue.

Solution

Update the affected freeradius packages.
