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.
