Description of the security update for Excel 2016: August 14, 2018

This security update resolves vulnerabilities in Microsoft Office that could allow remote code execution and information disclosure if a user opens a specially crafted Office file. To learn more about these vulnerabilities, see Microsoft Common Vulnerabilities and Exposures CVE-2018-8375, Microsoft Common Vulnerabilities and Exposures CVE-2018-8379, and Microsoft Common Vulnerabilities and Exposures CVE-2018-8382.

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).

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

• Excel hangs intermittently in some cases. For example, Excel hangs when you paste many pictures into a worksheet and type text into cells. It also hangs when you paste a picture into a worksheet and then resize or move the picture.

• Excel hangs in specific cases. For example, tapping near the New Sheet button in a workbook on a touch-enabled computer can cause Excel to hang.

• Assume that you open several Excel workbooks in Protected view. When you unprotect and edit one of them, high CPU usage occurs.

• Assume that you use an XLL add-in to store and retrieve binary data in a workbook. Then, you open the workbook by Automation (Workbooks.Open). Excel crashes when xlGetBinaryName is called from a Workbook_Open event.

• This update shortens the German translation for the VLOOKUP function assistant help text.
