   For more complete information, refer to the Microsoft Security
   Bulletin Summary for July, 2005.


Overview

   Microsoft has released updates that address critical vulnerabilities
   in Windows, Office, and Internet Explorer. Exploitation of these
   vulnerabilities could allow a remote, unauthenticated attacker to
   execute arbitrary code on an affected system.


I. Description

   Microsoft Security Bulletins for July, 2005 address vulnerabilities in
   Windows, Office, and Internet Explorer. Further information is
   available in the following Vulnerability Notes:


   VU#218621 - Microsoft Word buffer overflow in font processing routine

   A buffer overflow in the font processing routine of Microsoft Word may
   allow a remote attacker to execute code on a vulnerable system.
   (CAN-2005-0564)


   VU#720742 - Microsoft Color Management Module buffer overflow during
   profile tag validation

   Microsoft Color Management Module fails to properly validate input
   data, allowing a remote attacker to execute arbitrary code.
