RHEL 3 : freeradius (RHSA-2003:386)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated FreeRADIUS packages are now available that fix a denial of
service vulnerability.

FreeRADIUS is an Internet authentication daemon, which implements the
RADIUS protocol. It allows Network Access Servers (NAS boxes) to
perform authentication for dial-up users.

The rad_decode function in FreeRADIUS 0.9.2 and earlier allows remote
attackers to cause a denial of service (crash) via a short RADIUS
string attribute with a tag, which causes memcpy to be called with a
-1 length argument, as demonstrated using the Tunnel-Password
attribute. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0967 to this issue.

Users of FreeRADIUS are advised to upgrade to these erratum packages
containing FreeRADIUS 0.9.3 which is not vulnerable to these issues.
