Description

Identify and drop oversized and irregular ICMP packets, which protects against the ping of death attack. In the ping of death attack, the attacker sends the target ping packets whose IP datagram length (ip_len) exceeds the maximum legal length (65,535 bytes) for IP packets, and the packets are fragmented. When the target attempts to reassemble the IP packets, a buffer overflow might occur, resulting in system crashing, freezing, and restarting.
