<blah blah blah>

Compiles a shared library in /tmp/own.so containing the functions

int getuid() { return 0; }
int geteuid() { return 0; }
int getgid() { return 0; }
int getegid() { return 0; }

and executes /bin/sh with LD_PRELOAD=/tmp/own.so

Pretty lame. Protip: "hellc0de" containing lots of \x61-\x7f looks
fake.

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...

Regards,

Andrew.
