Description of the security update for SharePoint Server 2019: February 12, 2019

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 Common Vulnerabilities and Exposures CVE-2019-0594 and Microsoft Common Vulnerabilities and Exposures CVE-2019-0604.

Note To apply this security update, you must have the release version of Microsoft SharePoint Server 2019 installed.

This security update contains the following improvements and fixes:

• When you run a search query that contains the SortList query parameter by using the REST interface, the query fails and generates a SearchServiceException exception. This can occur because the SortList parameter is case-sensitive.

• When you index a document for search, the number of unique tokens per field is now increased from 10,000 to 1,000,000 before the document field is truncated.

• The Search Service Application interface is now public. It is now possible to create a custom search application that uses the Search Service Application interface.

• This update makes improvements to enable the new Japanese Era in SharePoint Server 2019 when it becomes available.

• This update fixes an issue that affects SharePoint integration with Office Online Server. When you select the Open in Word Online option for a Word document, the document does not appear. This fix also improves the translation and localization of various strings in the modern features, such as modern lists and modern libraries.

• This update fixes the Help link on some SharePoint Central Administration pages to point to Central Administration help instead of user help.

• When you create a team site or classic team site in the central administration of SharePoint Server 2019 on-premises, the description references Office 365. This is inaccurate. The description is now more accurate.

• This update adds the ability to change a task's duration type through the client-side object model (CSOM) after the task is created.

• You can't set the description of a lookup table value to blank through the client-side object model (CSOM).

• You can't get all the details of a dependency link, such as the lag duration and project UID properties, through the client-side object model (CSOM).

• After a v2v upgrade from SharePoint Server 2016 to SharePoint Server 2019, PerformancePoint and User Profile service application databases do not have the expected compatibility level.

• Because the multi-tenancy feature is unavailable in SharePoint Server 2019 on-premises, this update removes the multi tenancy option on the central administration page (Irmadmin.aspx) in SharePoint Server 2019.

• Blob caching fails because the new logic to replace metabase access requires the local administrator permission for the application pool account.
