CentOS Errata and Security Advisory CESA-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. (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.
