Fedora Legacy Update Advisory

Synopsis: Updated freeradius packages fix security flaws
Advisory ID: FLSA:2187
Issue date: 2005-02-01
Product: Fedora Core
Keywords: Bugfix
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=2187
CVE Names: CAN-2004-0938 CAN-2004-0960 CAN-2004-0961

1. Topic:

Updated freeradius packages that fix a number of denial of service vulnerabilities as well as minor bugs are now available.

FreeRADIUS is a high-performance and highly configurable free RADIUS server designed to allow centralized authentication and authorization for a network.

2. Relevant releases/architectures:

Fedora Core 1 - i386

3. Problem description:

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.

Please note that the pam config file included in these packages was renamed to /etc/pam.d/radiusd.

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 all previously released errata relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs.

Please note that this update is also available via yum and apt. Many people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. This assumes that you have yum or apt-get configured for obtaining Fedora Legacy content. Please visit http://www fedoralegacy.org/docs for directions on how to configure yum and apt-get.

5. Bug IDs fixed:

http://bugzilla.fedora.us - 2187 - Freeradius < 1.0.1 DoS and remote crash

6. RPMs required:

Fedora Core 1:



7. Verification:

SHA1 sum Package Name


These packages are GPG signed by Fedora Legacy for security. Our key is available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the sha1sum with the following command:

sha1sum filename
