---------------------------------------------------------------------

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

following Web page for the System Administration or Customization
guide specific to your system:

127168 - rebuilding freeradius picks up system libeap rather than package libeap
127162 - zlib-devel is missing from BuildRequires in spec file
130606 - Missing buildrequires in freediag
130613 - radiusd.conf specifies other pam-auth than file installed in /etc/pam.d
135825 - CAN-2004-0938 Freeradius < 1.0.1 DoS and remote crash (CAN-2004-0960, CAN-2004-0961)
