Detail

Problem 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Problem description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188
