The Ping of Death exploits the fragmentation vulnerability of large ICMP ECHO request packets by sending an illegal packet with more than 65K of data, creating a buffer overflow.
*a TCP sequence number attack, which exploits the nonrandom predictable pattern of TCP connection sequence numbers to spoof a session.
*a TCP SYN attack, is a DoS attack that exploits the TCP threeway handshake. The attacker rapidly generates randomly sourced SYN packets filling the target's connection queue before the connection can timeout.
*land.c attack, is also a DoS attack that exploits TCP SYN packets. The attacker sends a packet that gives both the source and destination as the target's address, and uses the same source and destination port.
