After successfully exploiting the vulnerability, an attacker could run arbitrary code with elevated privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.</p> <p>The security update addresses the vulnerability by correcting the way Windows Installer handles certain filesystem operations.</p>
