Description of the security update for SharePoint Enterprise Server 2016: November 12, 2019

Summary

This security update resolves an information disclosure vulnerability that exists in Microsoft SharePoint if an attacker uploads a specially crafted file to the SharePoint Server. To learn more about the vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2019-1443.

Note To apply this security update, you must have the release version of Microsoft SharePoint Enterprise Server 2016 installed on the computer.

This public update delivers Feature Pack 2 for SharePoint Server 2016. Feature Pack 2 contains the following feature:

• SharePoint Framework (SPFx)

This public update also delivers all the features that were included in Feature Pack 1 for SharePoint Server 2016, including the following:

• Administrative Actions Logging

• MinRole enhancements

• SharePoint Custom Tiles

• Hybrid Taxonomy

• OneDrive API for SharePoint on-premises

• OneDrive for Business modern user experience (available to Software Assurance customers)

The OneDrive for Business modern user experience requires an active Software Assurance contract at the time that the experience is enabled, either by installing the public update or by manual enablement. If you don't have an active Software Assurance contract at the time of enablement, you must turn off the OneDrive for Business modern user experience.

Improvements and fixes

This security update contains improvements and fixes for the following nonsecurity issues in SharePoint Server 2016:

• Removes the Hybrid Auditing feature from SharePoint Server 2016.

• Reduces the severity of certain upgrade sequence messages from WARNING to INFO. These messages indicate that the upgrade action doesn't have to make any changes because its database extension is currently not enabled in the database. For example, you will no longer see upgrade messages such as the following be labeled as warnings:
  
  "Ignoring upgrade sequence: Microsoft.SharePoint.BusinessData.Upgrade.BdcDatabaseExtensionUpgradeSequence because related content database extension Microsoft.SharePoint.BusinessData.SharedService.BdcDatabaseExtension is not enabled."

• Fixes an issue that causes failures when you upload documents that contain links to very long URLs.

• Fixes an issue in which the web part displays no content when users visit a Content Search Web Part (CSWP) from the Google's page viewer or set the AlwaysRenderOnServer boolean in a Content Search Web Part (CSWP) to True.

• Fixes an issue in which the Product Version Timer Job fails on dedicated Search and Distributed Cache servers.

• Fixes an issue in which Publishing Cache items are missing page field data after the IIS app pool restarts.

• When a web application uses Default Configuration to configure SAML-based claims authentication by using Active Directory Federation Services (AD FS) and the people picker account resolution, users from an external trusted domain experience the following issues:

  • They cannot log on to a site.

  • They cannot be resolved by People Picker if they are set up by using ADFS and have "Email" as the identity claim.

This security update contains a fix for the following nonsecurity issue in Project Server 2016:

• In a Project Web App (PWA) project in which a proposed resource is replaced by a committed resource (or vice versa), existing assignments aren't replaced by the new resource. Instead, the assignments are lost.
