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 Security Bulletin MS15-110. Microsoft Office 2016 for Mac includes versions of Word, Excel, PowerPoint, OneNote, and Outlook that are designed for the Mac and yet are unmistakably Office. The October 13, 2015, update provides fixes for issues in the Office 2016 for Mac Suite (Word, Excel, PowerPoint, OneNote, and Outlook).
Note To install this update, you must be running OS X Yosemite 10.10 or a later version, and you must have a valid Microsoft Office 365 subscription. Additionally, see more information about Office 365 Subscription options. If you already have Office 2011 for Mac installed, you can run Office 2011 and Office 2016 side-by-side.
For a complete list of affected versions of Microsoft Office software, see KB 3096440.
