RHSA-2003-386: freeradius

Vulnerability Assessment Summary
Check for the version of the freeradius packages

Detailed Explanation for this Vulnerability Assessment

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 permits Network Access Servers (NAS boxes) to perform
authentication for dial-up users.

The rad_decode function in FreeRADIUS 0.9.2 and earlier permits 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.
