## Description

<p>A security feature bypass vulnerability exists in Microsoft Office software by not enforcing macro settings on an Excel document. The security feature bypass by itself does not allow arbitrary code execution. To successfully exploit the vulnerability, an attacker would have to embed a control in an Excel worksheet that specifies a macro should be run.   To exploit the vulnerability, an attacker would have to convince a user to open a specially crafted file with an affected version of Microsoft Office software.   The security update addresses the vulnerability by enforcing macro settings on Excel documents.</p>
