VULHUB ™

The Cisco VPN Client is Virtual Private Network software. Some versions of the VPN Client are vulnerable to a denial of service attack. When vulnerable clients receive a specific IKE packet with a zero length payload, the VPN client will consume all available processor time. This may result in a denial of service condition, and require that the VPN client process be manually killed and restarted in order to regain normal functionality.
