freeradius -- arbitrary code execution for TLS-based authentication

freeRADIUS security team reports:

Overflow in EAP-TLS for 2.1.10, 2.1.11 and 2.1.12.

The issue was found by Timo Warns, and communicated to security@freeradius.org. A sample exploit for the issue was included in the notification.

The vulnerability was created in commit a368a6f4f4aaf on August 18, 2010. Vulnerable versions include 2.1.10, 2.1.11, and 2.1.12. Also anyone running the git "master" branch after August 18, 2010 is vulnerable.

All sites using TLS-based EAP methods and the above versions are vulnerable. The only configuration change which can avoid the issue is to disable EAP-TLS, EAP-TTLS, and PEAP.

An external attacker can use this vulnerability to over-write the stack frame of the RADIUS server, and cause it to crash. In addition, more sophisticated attacks may gain additional privileges on the system running the RADIUS server.

This attack does not require local network access to the RADIUS server. It can be done by an attacker through a WiFi Access Point, so long as the Access Point is configured to use 802.1X authentication with the RADIUS server.
