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 MS17-014.

Note To apply this security update, you must have the release version of Service Pack 1 for Microsoft SharePoint Foundation 2013 installed on the computer.

For a complete list of affected versions of Microsoft Office software, see Microsoft Knowledge Base article 4013241.

Improvements and fixes

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

  • When you browse to the action links of a question or answer (such as the Edit or Reply link) in a discussions list, no context of that message appear in the action links. Therefore, screen readers can't detect the context of the message that you focus on. The update adds a simple text string to all action links that are part of the message body.

  • In an announcements list, the email attachment of an email item is lost if the attached .eml file title contains specific characters.

  • After you enter and format text in a table of a content editor web part in a site in Internet Explorer, Internet Explorer scrolls the page unexpectedly.

  • If your permission isn't enabled on the Manage Permissions page, you don't receive email notification as expected even if you are granted permissions.

  • When you try to apply a filter to a list view, you receive the following error message if this view is grouped by a calculated column:

SqlError: 'ORDER BY items must appear in the select list if SELECT DISTINCT is specified.

  • After you migrate from classic-mode to claims-based authentication in Microsoft SharePoint 2013, you receive an exception when you try to access the SPFileVersion.CreatedBy property of a document.

  • When the subject line of a SharePoint alert email is longer than 75 characters and contains a mix of single-byte and double-byte characters, a carriage return line feed (CLRF) can occur between the two bytes of a double-bite character, causing the string to get corrupted..

  • Headings structure is incorrect in blogs basic view.

  • When you start a crawl for a web application that's migrated from SharePoint Server 2010, the crawl fails, and the content isn't searchable. This issue occurs because the connector retrieves the TenantId property two times.

  • When you open a document in Word Web App, you receive the following error message if there are special characters in the URL of the document:

Sorry, there was a problem and we can't open this document.

  • When you try to restore a site that's backed up in a site collection, you receive the following error message if the site collection lock is set to No Access:

Access to the web site has been blocked. The site isn't accessible and isn't displayed on Central Admin.

  • It's difficult for a screen reader to understand the structure between sections on a discussion board because there's only one heading. This update adds h2 and h3 labels to discussion boards for better screen reading.

  • In SharePoint Server 2013 on-premises, you can't not be redirected to SharePoint Online to create sites.

SharePoint Server 2013 and SharePoint Foundation 2013
