Executive Summary
A remote code execution vulnerability exists when Git for Visual Studio improperly sanitizes input. An attacker who successfully exploited this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
To exploit the vulnerability, an attacker would first need to convince the user to clone a malicious repo.
The security update addresses the vulnerability by correcting how Git for Visual Studio validates command-line input.

FAQ
I want to install the latest supported service baseline for Visual Studio. Do I need to install the previous versions first?
No. For both Visual Studio 2019 and Visual Studio 2017, the latest supported servicing baseline is cumulative. For example, if you need to install Visual Studio 2019 version 16.4 you do NOT first have to install any previous versions. See Visual Studio 2019 version 16.4 Release Notes for more information.
