Summary

This security update resolves a remote code execution vulnerability that exists in Microsoft Project software if the software does not check the source markup of a file. To learn more about the vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2020-1449.

Note To apply this security update, you must have the release version of Project 2016 installed on the computer.
