Description
Cisco IOS before 12.3-7-JA2 on Aironet Wireless Access Points (WAP) allows remote authenticated users to cause a denial of service (termination of packet passing or termination of client connections) by sending the management interface a large number of spoofed ARP packets, which creates a large ARP table that exhausts memory, aka Bug ID CSCsc16644.
