## Description

<p>A security feature bypass vulnerability exists in Microsoft Windows when the Client-Server Run-time Subsystem (CSRSS) fails to properly manage process tokens in memory.</p> <p>An attacker who successfully exploited this vulnerability could run arbitrary code as an administrator. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.</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 and take control of an affected system.</p> <p>The security update addresses the vulnerability by correcting how Windows manages process tokens in memory.</p>
