An OpenDocument Presentation .ODP or Presentation Template .OTP file
can contain invalid presentation elements that lead to memory corruption when
the document is loaded in Apache OpenOffice Impress. The defect may cause the
document to appear as corrupted and OpenOffice may crash in a recovery-stuck
mode requiring manual intervention. A crafted exploitation of the defect can
allow an attacker to cause denial of service (memory corruption and application
crash) and possible execution of arbitrary code.

- For defects such as those involved in CVE-2016-1513, documents can
be crafted to cause memory corruption enough to crash Apache OpenOffice
Impress. However, the conditions under which arbitrary code can be executed are
complex and difficult to achieve in an undetected manner.
+ If you are unable to apply the Hotfix to Apache OpenOffice 4.1.2
(after updating to that version, if necessary), there are other
+ precautions that can be taken. These precautions are applicable in
avoiding other possible exploits as well.

An important layer of defense for all such cases is to avoid
operating Apache OpenOffice (and any other personal productivity programs)
under a computer account that has administrative privileges of any kind. While
installation of Apache OpenOffice requires elevated privileges and user
permission on platforms such as Microsoft Windows, operation of the software
does not.
<br /><br />
Keeping antivirus/antimalware software current is also important.
This will serve to identify and distinguish suspicious documents that involve
the exploit, avoiding confusion with documents that are damaged and/or fail for
other reasons.

- Impress cannot be used to directly produce documents having the
CVE-2016-1513-related defect. Impress-authored .ODP and .OTP documents of an
user's own that exhibit any of these characteristics are not the result of an
exploit. They may be consequences of a separate Impress defect that should be
reported.
- <br /><br />
- For .ODP and .OTP files from unknown or suspicious sources, any
automatic closing on opening or failing of OpenOffice Impress can be checked by
opening the file in an OpenDocument Presentation application that is not
vulnerable to the defective document formatting involved in CVE-2016-1513.
Current releases of LibreOffice and Microsoft Office PowerPoint (for .ODP
files), including PowerPoint Online, are known to avoid the defect. Other
ODF-supporting software may be successful. The resulting presentation may
appear corrupted or incomplete and need not reflect an actual exploit attempt.
Saving the document as a new presentation file will be exploit-free either way.

- To report a suspicious document from an external source and for
which OpenOffice Impress crashes, preserve the file exactly and report to <a
href="mailto:[email protected]";>[email protected]</a>.
Await further instructions for submission of the file itself. Do not post
files having suspected exploits to mailing lists, the issue-reporting system,
or any other public location.
