Schmitz Microsoft has issued version 15.23 of its [1]Office 2016 suite, which patches a critical security vulnerability as well as provides a number of fixes and improvements to the individual apps in the suite. 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 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 that was introduced in version 15.22, resolves an issue with AutoCorrect preferences, and reintroduces the Edit Message feature. On the [2]security front, both Office 2016 and Office 2011 (which has been updated to [3]version 14.6.5) resolve a memory corruption vulnerability that allow remote attackers to execute arbitrary code via an Office document.
