This vulnerability is quite well known and was earlier commonly used to hang remote systems (or even force them to reboot) so that no users can use its services. This exploit no longer works, as almost all system administrators would have upgraded their systems making them safe from such attacks.

The following Ping command creates a giant datagram of the size 65540 for Ping. It might hang the victim's computer:
