## Description

<p>A remote code execution vulnerability exists when Microsoft Publisher fails to utilize features that lock down the Local Machine zone when instantiating OLE objects. An attacker who successfully exploited the vulnerability could force arbitrary code to be executed in the Local Machine zone.</p> <p>To exploit the vulnerability, the attacker could send a specially crafted Publisher document to a victim. The user would then need to open the document in Publisher to trigger the vulnerability.</p> <p>This update addresses the vulnerability by ensuring that Publisher properly utilizes built-in OS functionality to lock down the Local Machine zone.</p>
