Title:RedHat Security Advisory RHSA-2006:0271

The remote host is missing updates announced in
advisory RHSA-2006:0271.

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 an attacker 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.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date

Risk factor : High
