Description of the security update for SharePoint Enterprise Server 2016: October 8, 2019

Applies to: SharePoint Server 2016

Summary


This security update resolves a spoofing vulnerability that exists if Microsoft SharePoint Server does not correctly sanitize a specially crafted web request to an affected SharePoint server. To learn more about the vulnerability, see the following security advisories: 

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:

  • Administrative Actions Logging
  • MinRole enhancements
  • SharePoint Custom Tiles
  • Hybrid Auditing (preview)
  • 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 installation of 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 fixes for the following nonsecurity issues in SharePoint Server 2016:

  • Fixes a problem with the Convert-SPWebApplication cmdlet when the User Principal Name (UPN) is set as an identifier. Now you will be able to move SharePoint authentication to the Active Directory Federation Services (AD FS) Identity Provider by using following command:


    Convert-SPWebApplication -Identity $wa -From CLAIMS-WINDOWS -To CLAIMS-TRUSTED-DEFAULT -TrustedProvider $tp

  • Fixes the issue that affects access to the host-named site collection if one of the sites is deleted and users lose access to other sites for about a day. Now users will be able to access all the sites by running following command in PowerShell even though one of the sites is deleted:
     

    $config = Get-SPSecurityTokenServiceConfig

    $config.WindowsModeIgnoreCache = $true

    $config.Update()

  • Users who have limited permissions on a list or document library but have approve-level permissions on a folder can now approve multiple items or documents in the folder. To complete the approval, you must select the items in the folder and use the Approve/Reject option on the Ribbon.
  • SharePoint patching may copy more folders than are necessary for side-by-side patching. This consumes additional hard drive space. This update fixes the issue by restricting copying to only the folders that are necessary for side-by-side patching.

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

  • Makes changes to display the new Japanese era name for date format samples in Date Format in Project Web App (PWA) sites.
  • The OwnerId property is now available to update the project owner through a REST call. The type of this property is String, but it accepts only the user's numeric ID.
  • You cannot delete resource calendar exceptions through the client-side object model (CSOM). This issue occurs after you install update 4464594.
  • If the stage status information text contains special characters such as an ampersand (&), workflows fail.
  • When the Schedule Variance Percentage (SVP) or Cost Variance Percentage (CVP) earned value becomes very large, this creates an overflow condition. This causes the client-side object model (CSOM) or REST calls that are made while accessing the project to fail. The SVP and CVP values now have a lower limit of "-100%" and upper limit of "100%."
