The remote host has an application installed that is missing a security update.

Description

The Microsoft Visual Studio Code .NET Install Tool for Extension Authors Extension is prior to version 1.2.0. It is, therefore, affected by an elevation of privilege vulnerability due to inaccurately scoped permissions being set on downloaded .NET install scripts.
