Cisco is urging admins to update their wireless LAN hardware
following the discovery of multiple vulnerabilities in its enterprise
Wi-Fi kit.

Security flaws in Cisco Wireless LAN Controllers, Cisco Catalyst 6500
Wireless Services Modules (WiSMs), and Cisco Catalyst 3750 Integrated
Wireless LAN Controllers create a mechanism for hackers to knock over

All Cisco Wireless LAN Controllers running version 4.2 of the network
giant's software are affected by a pair of denial of service flaws. A
third DoS flaw affects software versions 4.1 and later.
