This security update resolves an information disclosure vulnerability that exists when Microsoft Word incorrectly discloses the contents of its memory. To learn more about the vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2020-1502.

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

Improvements and fixes

This security update contains fixes for the following issues in SharePoint Server 2019. To fix these issues completely, you have to install KB 4484472 together with this update:

  • The view name does not change when you use Group By.

  • Adding a document link does not return you to the library.

  • A multichoice person column is not displayed correctly in modern view.

  • The Aria-labelledby attribute value is invalid.

  • The home page title is not descriptive enough.

  • A banner landmark must not be contained inside another landmark.

  • The title of Frame is missing in Create Site.

  • If a user navigates to a custom list and opens the Links list in JAWS by using the Alt+F7 keyboard shortcut to see all links on the page, each item in the custom list shows the Open Menu link to open the Edit Control Block (ECB) menu. In this situation, it is not possible to determine which item each link belongs to.
