Description of the security update for Excel 2016: November 14, 2017

Applies to: Excel 2016

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-2017-11877 and Microsoft Common Vulnerabilities and Exposures CVE-2017-11878.

Note To apply this security update, you must have the release version of Excel 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).

Known issues


  • Symptoms
    After you install this update, when you click on a shape that has a digitally signed macro assigned to it, you may receive the following error:
    Cannot run the macro.
    The macro may not be available in this workbook or all macros may be disabled.
    Workaround
    Currently, the only recommended workaround is to update the workbook so there isn’t a shape that is used to trigger a digitally signed macro.

    Note We do not recommend you uninstall or delay the installation of this security update because of this issue. This security update resolves a security feature bypass vulnerability that can expose unsafe workflows when using macros, trusted certificates, and shapes.

    Microsoft is researching this problem and will post more information in this article when the information becomes available.
