Cisco Security Advisory (19/10/2007):

Cisco have released an advisory warning of a DoS vulnerability on some of their EAP authenticators, see:

http://www.cisco.com/warp/public/707/cisco-sr-20071019-eap.shtml

According to the advisory, the following products are vulnerable if they have an EAP authenticator enabled:

- Access Points and 1310 Wireless Bridges running Cisco IOS in autonomous mode

- All Cisco switches running affected versions of Cisco IOS

- All Cisco switches running affected versions of Cisco CatOS

A firmware upgrade seems to be the recommended solution.

According to the advisory, the following are NOT vulnerable:

Access Points

- Access Points running VxWorks (Cisco 1000s)

- Lightweight Access Point (LAP) in local mode
