   Original release date: May 8, 2007
   Last revised--
   Source: US-CERT


Systems Affected

     * Microsoft Windows
     * Microsoft Windows Server
     * Microsoft Internet Explorer
     * Microsoft Office for Windows and Mac OS X
     * Microsoft Exchange

Overview

   Microsoft has released updates that address critical vulnerabilities
   in Microsoft Windows, Internet Explorer, Office, Exchange,
   Cryptographic API Component Object Model (CAPICOM), and BizTalk.
   Exploitation of these vulnerabilities could allow a remote,
   unauthenticated attacker to execute arbitrary code or cause a denial
   of service on a vulnerable system.


I. Description

   Microsoft has released updates to address vulnerabilities that affect
   Microsoft Windows, Internet Explorer, Office, Exchange, CAPICOM, and
   BizTalk as part of the Microsoft Security Bulletin Summary for May
   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.

   In addition a previously disclosed vulnerability in Microsoft DNS RPC
   is addressed in this update.

   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 May
   2007 Security Bulletins. The Security Bulletins describe any known
   issues related to the updates. Note any known issues described in the
   Bulletins and test for any potentially adverse effects in your
   environment.

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