Overview

   Microsoft has released updates that address critical vulnerabilities
   in Microsoft Windows, Windows Secure Channel, Internet Explorer,

   system.


I. Description

   Microsoft has released updates to address vulnerabilities that affect
   Microsoft Windows, Windows Secure Channel, Internet Explorer, Win32
   API, Visio, Outlook Express and Windows Mail as part of the Microsoft
   Security Bulletin Summary for June 2007. The most severe
   vulnerabilities could allow a remote, unauthenticated attacker to
   execute arbitrary code or cause a denial of service on a vulnerable
   system.

   Further information about the vulnerabilities addressed by these
   updates is available in the Vulnerability Notes Database


II. Impact

   A remote, unauthenticated attacker could execute arbitrary code on a
   vulnerable system. An attacker may also be able to cause a denial of
   service.


III. Solution

Apply updates from Microsoft

   Microsoft has provided updates for these vulnerabilities in the June
   2007 Security Bulletins. The Security Bulletins describe any known
   issues related to the updates. Administrators are encouraged to note
   any known issues that are described in the Bulletins and test for any
   potentially adverse effects.

   System administrators may wish to consider using an automated patch
   distribution system such as Windows Server Update Services (WSUS).
