GEN:SID 1:499
Message ICMP Large ICMP Packet
Summary This event is generated when a large ICMP packet is detected. Also known
as the "Ping of Death".
Impact Denial of Service (DoS) by system crash or bandwidth utilisation.
Detailed Information Some implementations of the IP stack may result in a system crash
or may hang when a large ICMP packet is sent to them. Alternatively
a large number of these packets may result in link saturation,
especially where bandwidth is limited.

This attack was prevalent a number of years ago when the TCP/IP stack of
a number of operating systems could not handle large packet payloads.
Affected Systems Multiple older systems.
Attack Scenarios A malicious individual may send a series of large ICMP packets
to a host with the intention of either crashing or hanging the host,
or to saturate the available bandwidth.
Ease of Attack Simple.
Corrective Action
