           <strong>Windows Installer Execution of Arbitrary Code with
               Elevated Privileges
           </strong>
         </p>

         <p>
           <strong>Version 1.0</strong>
         </p>

         <p>
           Announced October 11, 2016
         </p>

         <p>
           <strong>Description</strong>
         </p>

         <p>
           The Apache OpenOffice installer for Winodws contained a defective
           operation that allows execution of arbitrary code with elevated
           privileges.
         </p>
         <p>The location in which the installer is run may have been
             previously poisoned by a file that impersonates a dynamic-link
             library that the installer depends upon.  The counterfeit is
             operated instead because of a search path defect in the
             installer.  The counterfeit will be operated under the
             administrative privileges of the OpenOffice installer,
             compromising the users's PC.

           <strong>Severity: Medium</strong>

         <p>
           <strong>Versions Affected</strong>
         </p>

         <p>
           All Apache OpenOffice versions 4.1.2 and older are affected.<br />
           OpenOffice.org versions are also affected.
         </p>

         <p>
           <strong>Mitigation</strong>
         </p>

         <p>
           Install Apache OpenOffice 4.1.3 for the latest maintenance and
           cumulative security fixes.  Use the Apache OpenOffice
           <a href="https://www.openoffice.org/download/">download page</a>.
         </p>

         <p>
           <strong>Defenses and Work-Arounds</strong>
         </p>

         <p>
           If you are unable to update to 4.1.3, there are other precautions
           that can be taken.  These precausions are also recommended as protection against other software that may have the vulnerability.
           <br /><br />
           When executing .exe installers, ensure that the installer is in a file folder that has no other files but the installer .exe file.
           <br /><br />
           If an installer proposes a folder to extract the setup files
           into before the actual install, choose the name of a folder that is not in use.  Delete such a folder of setup files after the installation completes successfully.  To reinstall without
           downloading again, preserve the installer .exe on private
           removable storage.
