Vulnerability Summary

Denial of Service in Cisco DSL CPE via Large Packet Flooding

Remote attackers can disrupt Cisco DSL CPE devices with CBOS 2.4.4 or older. They can send a big packet to the DHCP port, send a big packet to the Telnet port, or flood the CPE with large packets. This makes the devices hang or use up too much memory by overloading the TCP/IP stack.
