Detail

Severity Rating: Critical
Revision Note: V2.1 (December 18, 2015): Bulletin revised to correct the Updates Replaced for 3101532 and 3114342, and to add a workaround for CVE-2015-6172. This is an informational change only. Customers who have successfully installed the updates do not need to take any further action.
Summary: This security update resolves vulnerabilities in Microsoft Office. 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. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
