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 MS15-116.

After you apply this security update, you may see a popup window that states that a website wants to open web content in protected mode in Internet Explorer. See Updates to change the way that Internet Explorer interacts with features in Microsoft Office applications for more information.

Improvements and fixes

• Adds the insert picture API to Office Add-ins for Word 2013, Excel 2013, and PowerPoint 2013. 
  
• Adds two new add-in APIs under CustomXmlNode: getTextAsync and setTextAsync. These two new APIs also provide a way add a text value to a built-in CustomXmlNode object when the node has no text value yet.
  
• This update also contains fixes for the following nonsecurity issues:
  • Assume that you have a document that has combo box content controls that are linked to custom XML parts in a document in Word 2013. After you select a value in one of these controls and then do an undo and a save operation, the type of some content controls is changed from combo box to rich text and loses the mapping to the node in the custom XML part.
    
  • When you use certain fonts to enter a nonbreaking hyphen to a document in Word 2013, a square is displayed instead of a nonbreaking hyphen.
    
  • The Do Not Forward business bar information string is cropped and isn't fully displayed in some non-English versions of Outlook 2013.
    
  • Assume that you have a document that has footnotes and both manual and automatic page breaks in Word 2013. You set the Numbering to Restart each page in the Footnote and Endnote dialog box. When you print a document in the background, footnote numbers in the printout are numbered consecutively instead of being restarted on each page.
