Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker convinces a user to view a specially crafted Office document with embedded content.

Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
