RHSA-2006-0271: freeradius Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the freeradius packages

Detailed Explanation for this Vulnerability Test

Updated freeradius packages that fix an authentication weakness are now

This update has been rated as having important security impact by the Red
Hat Security Response Team.

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

A bug was found in the way FreeRADIUS authenticates users via the MSCHAP V2
protocol. It is possible for a remote attacker to authenticate as a victim
by sending a malformed MSCHAP V2 login request to the FreeRADIUS server.

Please note that FreeRADIUS installations not using the MSCHAP V2 protocol
for authentication are not vulnerable to this issue.

A bug was also found in the way FreeRADIUS logs SQL errors from the
sql_unixodbc module. It may be possible for a possible hacker to cause FreeRADIUS
to crash or execute arbitrary code if they are able to manipulate the SQL
database FreeRADIUS is connecting to. (CVE-2006-4744)

Users of FreeRADIUS should update to these erratum packages, which contain
backported patches and are not vulnerable to these issues.
