This security update resolves vulnerabilities in Microsoft Office.
The security update addresses the vulnerabilities by correcting how:
Microsoft Office saves documents.
Click-to-Run components handle memory addresses.
affected versions of Office and Office components handle objects in memory.
Microsoft Outlook determines the end of MIME messages.
The most severe of the vulnerabilities could allow remote code execution if a user opens a specially crafted Microsoft Office file. An attacker who successfully exploited the vulnerabilities could run arbitrary code in the context of the current user.
