Title
Projected Filesystem Security Feature Bypass Vulnerability
Summary
<p>A security feature bypass vulnerability exists when a Windows Projected Filesystem improperly handles file redirections. An attacker who successfully exploited this vulnerability could delete a targeted file they would not have permissions to.</p>
<p>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.</p>
<p>The security update addresses the vulnerability by correcting how Windows Projected Filesystem handle file redirections.</p>
