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

This security update resolves a cross–site-scripting (XSS) vulnerability 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 Microsoft Common Vulnerabilities and Exposures CVE-2019-0778 and CVE-2019-0604.

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

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.
