## Description

<p>A denial of service vulnerability exists when a specially crafted file is opened in Microsoft Office.

Note that the denial of service would not allow an attacker to execute code or to elevate the attacker's user rights.</p> <p>For an attack to be successful, this vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office. In an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted file to the user and by convincing the user to open the file.</p> <p>The security update addresses the vulnerability by correcting how Microsoft Office handles objects in memory.</p>
