Max Ping Size
PING (ICMP echo request) is a program that uses ICMP protocol to check whether a
remote machine is up. A request is sent by the client, and the server responds with a reply
echoing the client's data.
An attacker can echo the client with a large amount of data, causing a buffer overflow.
You can protect against such attacks by limiting the allowed size for ICMP echo requests.
