Description of the security update for Word 2016: January 9, 2018

View products that this article applies to.

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 the vulnerabilities, go to the following Common Vulnerabilities and Exposures (CVE).

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

Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home (see Determining your Office version).

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:
  • In a Word 2016 document, when you right-click to select text and then drag it to another location, it does not work.

  • Word 2016 crashes after you open a document that contains ActiveX controls in an Active Document Container.

  • When you use Office add-in-rich APIs to delete the last paragraph in an Office document, the new last paragraph may take some format of the original last paragraph. After you install this update, the new last paragraph will keep its original format unchanged.
  • This update improves Office application startup performance by skipping unnecessary scanning of Microsoft Word documents that are local and not encrypted.
