Microsoft Office 2016 15.23 and Office 2011 14.6.5

by Agen G. N. Schmitz

Microsoft has issued version 15.23 of its Office 2016 [1] application suite, which patches a critical security vulnerability and provides some fixes and improvements. You can now export documents, presentations, and spreadsheets to the OpenDocument format, add any command you want to the ribbon for Word, Excel, and PowerPoint (requires an Office 365 subscription), and customize the Quick Access Toolbar. PowerPoint now also enables you to export a presentation for burning to disc, sending in email, or uploading to the Web. The Outlook update fixes a spike in CPU usage introduced in version 15.22, resolves an issue with AutoCorrect preferences, and reintroduces the Edit Message feature.

On the security front [2], both Office 2016 and Office 2011, which has been updated to version 14.6.5 [3], resolve a memory corruption vulnerability that enables remote attackers to execute arbitrary code via an Office document.
