This signature detects any IPv4 packets using the IP Mobility protocol. Many versions of Cisco IOS are vulnerable. Attackers can use a maliciously crafted sequence of packets that contain the IP Mobility protocol to cause a device, running Cisco IOS, to stop passing IPv4 traffic.
A denial of service vulnerability has been reported to exist in all hardware platforms that run Cisco IOS versions 11.x through 12.x. This issue may be triggered by a sequence of specifically crafted IPV4 packets. A power cycling of an affected device is required to regain normal functionality.
