Microsoft Updates for Multiple Vulnerabilities

   Original release date: April 10, 2007
   Last revised--
   Source: US-CERT


Systems Affected

     * Microsoft Windows
     * Microsoft Content Management Server
     * Microsoft Internet Explorer


Overview

   Microsoft has released updates that address critical vulnerabilities
   in Microsoft Windows and Microsoft Content Management Server.
   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 and Microsoft Content Management Server as part of
   the Microsoft Security Bulletin Summary for April 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.

   These updates include a fix to address a previously disclosed
   vulnerability in the Windows Client/Server Run-time Subsystem.

   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 or launch cross-site scripting attacks.


III. Solution

Apply updates from Microsoft

   Microsoft has provided updates for these vulnerabilities as part of
   the Microsoft Security Bulletin Summary for April 2007. 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 operating system environment.

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