CentOS 3 / 4 : freeradius (CESA-2006:0271)

high Nessus Plugin ID 21895

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated freeradius packages that fix an authentication weakness are now available.

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. (CVE-2006-1354)

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-2005-4744)

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

Solution

Update the affected freeradius packages.
