1. Summary:

Updated freeradius packages that fix a number of denial of service vulnerabilities as well as minor bugs are now available for Red Hat Enterprise Linux 3.

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



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 number of flaws were found in FreeRADIUS versions prior to 1.0.1. An attacker who is able to send packets to the server could construct carefully constructed packets in such a way as to cause the server to consume memory or crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0938, CAN-2004-0960, and CAN-2004-0961 to these issues.

Users of FreeRADIUS should update to these erratum packages that contain FreeRADIUS 1.0.1, which is not vulnerable to these issues and also corrects a number of bugs.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:

up2date
