An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data.<br /> To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.<br /> The security update addresses the vulnerability by correcting how Windows AppX Deployment Service handles hard links.
