Summary

This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see Microsoft Security Bulletin MS16-054.

Note To apply this security update, you must have the release version of Word 2016 installed on the computer.

For a complete list of affected versions of Microsoft Office software, see Microsoft Knowledge Base article KB3155544.

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:

  • This update adds support for Javanese Script.

  • Assume that you have a document that's digitally signed and the document has controls that's bound to the document metadata. After the document metadata is updated, Word 2016 still considers the document signature as valid.

  • Hebrew characters in footnote references are reversed in Word 2016.

  • When you paste mixed RTL and LTR plain text into a document in Word 2016, punctuation might appear on the wrong side of words.

  • Sometimes Word 2016 does not show a MacroButton field, and shows the following message instead:

    Display text cannot span more than one line!


  • After you enable and disable Split window for a document that has an ActiveX control in Word 2016, Word 2016 crashes.

  • Word 2016 may crash if a list item begins with a diacritic, and the list uses a space (instead of a tab) for indentation.

  • After you compare or combine two versions of a document that are coauthored by different coauthors in Word 2016, all OLE objects are marked as changed.

  • Autocorrect changes incorrect characters in the presence of diacritic in Word 2016.

  • Sometimes Word 2016 shows numbers incorrectly when the Numeral setting is set to Context in the Word Option dialog box.

  • When you scroll through a document that has an ActiveX control in Word 2016, the ActiveX control is switched to design mode.

  • The Send as PDF function is unavailable in Reading mode in SharePoint Server 2016.

  • Some symbol characters are changed to "1" unexpectedly in the following scenarios:

    • You send a RTF format email message that contains some symbol characters in Outlook 2016.

    • You copy and paste some symbol characters in Word 2016.
