Microsoft Updates for Multiple Vulnerabilities

   Original release date: November 13, 2007
   Last revised: --
   Source: US-CERT


Systems Affected

     * Microsoft Windows
     * Microsoft Windows DNS Server


Overview

   Microsoft has released updates that address critical vulnerabilities
   in Microsoft Windows and Microsoft Windows DNS Server. Exploitation of
   these vulnerabilities could allow a remote, unauthenticated attacker
   to execute arbitrary commands or to cause a Windows DNS server to
   provide incorrect DNS responses.


I. Description

   Microsoft has released updates to address vulnerabilities that affect
   Microsoft Windows and Microsoft Windows DNS Server as part of the
   Microsoft Security Bulletin Summary for November 2007. The most severe
   vulnerabilities could allow a remote, unauthenticated attacker to
   execute arbitrary commands or cause a Windows DNS server to provide
   incorrect DNS responses.

   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 commands on
   a vulnerable system. An attacker may also be able to cause a Windows
   DNS server to provide incorrect responses to DNS queries.


III. Solution

Apply updates from Microsoft

   Microsoft has provided updates for these vulnerabilities in the
   November 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 should consider using an automated patch
   distribution system such as Windows Server Update Services (WSUS).
