Impact :

    A remote attacker could send specially crafted packets to the
    FreeRADIUS server to deny service to other users by crashing the
    server.
  
Workaround :

    There is no known workaround at this time."

"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.

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 CVE-2004-0938,
CVE-2004-0960, and CVE-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."
