Author: JT Smith

Posted at Help-Net Security: "There is a vulnerability in how Cisco routers are handling CDP. By sending a large
amount of CDP neighbor announcements it is possible to consume all available router's
memory. That will cause a crash or some other abnormal behavior. This vulnerability is
assigned a Cisco bug ID CSCdu09909. You can see details of it if you have a valid
CCO account."
