Juniper Js Screen Monitor Ping Death

1.3.6.1.4.1.2636.3.39.1.8.1.1.1.1.6

The maximum allowable IP packet size is 65,535 bytes, including the packet header (typically 20 bytes long). An ICMP echo request is an IP packet with a pseudo header, which is 8 bytes long. Therefore, the maximum allowable size of the data area of an ICMP echo request is 65,507 bytes. However, many ping implementations allow the user to specify a packet size larger than 65,507 bytes. A grossly oversized ICMP packet can trigger a range of adverse system reactions such as denial of service (DoS), crashing, freezing, and rebooting. When the Ping Death option is enabled, the device detects and rejects such oversized and irregular packet sizes even when the attacker hides the total packet size by purposefully fragmenting it. This attributes counts the ping of death attack packets.
