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 Common Vulnerabilities and Exposures CVE-2018-0950

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:

  • When you view text in a reply or forward email that uses an automatic signature on an iOS device, the font color of the reply text is incorrect.

  • The end position of a bookmark is synced incorrectly during a co-authoring operation in Word 2016.

  • When you set the numeral shapes for Arabic text to Hindi numbers and then save a Word document that has Arabic text as a PDF file, the numbers in the Word document are incorrectly displayed as Arabic in the PDF file.

  • When you edit documents that are stored in an attachment field in a Microsoft Access database and then save the documents, you are unexpectedly prompted to "Save as."

  • If a Word document that contains OLE or OCX controls is embedded as an OLE object in another application, the controls appear in the wrong place when you scroll the document.

  • Improves performance for bookmark deletion by using programmatic method, such as deleting bookmarks through macros, VBA, and C#.

  • If the Windows system language is set to a complex script language, such as Thai, when you print a Word document that contains bullets, the bullets are printed incorrectly.

  • When you save a document in Word 2016 after you install KB 4011730, Word crashes.
