This whole exploit program is seemingly a massive obsfucation exercise.
Apart from the above, the prepare() function has "hidden" socket()
and sendto() calls to send a 64 byte parameter block to 213.73.91.29
port 864 (repeated 9 times).
The rest is repeated fork/wait/nice stuff that will probably have a
DoS effect on the system it's run on, but no privilege elevation...
