Applies to: Excel 2016


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-2018-8574 and Microsoft Common Vulnerabilities and Exposures CVE-2018-8577.
Note To apply this security update, you must have the release version of Microsoft Excel 2016 installed on the computer.

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues:
  • When you right-click the Excel icon in the taskbar and select Close all windows, Excel 2016 crashes sometimes.
  • When you save a workbook that contains external references to cells that contain metadata from another workbook, for example, a rich data type value, Excel 2016 crashes.
  • When you programmatically copy a very hidden sheet to a new workbook by using the Worksheet.Copy method, Excel 2016 crashes.
  • This update adds the translation for the Ctrl shortcut key in the Record Macro dialog in the German version.
