Install Apache OpenOffice 4.1.3 for the latest maintenance and
cumulative security fixes. Use <https://www.openoffice.org/download/>.

Defenses and Work-Arounds:

If you are unable to update to 4.1.3, there are other
precautions that can be taken. These precautions are also
recommended as protection against other software that may
have the vulnerability.

When executing .exe installers, ensure that the installer
is in a file folder that has no files but the installer
.exe file.

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.
