Microsoft Security Bulletin MS14-023 - Important

Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2961037)

Published: May 13, 2014

Version: 1.1

This security update resolves two privately reported vulnerabilities in 
Microsoft Office. The most severe vulnerability could allow remote code 
execution if a user opens an Office file that is located in the same network 
directory as a specially crafted library file. An attacker who successfully 
exploited this vulnerability could gain the same user rights as 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

This security update is rated Important for supported editions of Microsoft 
Office 2007, Microsoft Office 2010, and Microsoft Office 2013.

Affected Software

Microsoft Office 2007 
Microsoft Office 2010
Microsoft Office 2013 and Microsoft Office 2013 RT

Vulnerability Information

Microsoft Office Chinese Grammar Checking Vulnerability - CVE-2014-1756

A remote code execution vulnerability exists in the way that affected Microsoft 
Office software handles the loading of dynamic-link library (.dll) files. An 
attacker who successfully exploited this vulnerability could take complete 
control of an affected system. An attacker could then install programs; view, 
change, or delete data; or create new accounts with full user rights. 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.

Token Reuse Vulnerability - CVE-2014-1808

An information disclosure vulnerability exists when affected Microsoft Office
software does not properly handle a specially crafted response while attempting 
to open an Office file hosted on the malicious website. An attacker who 
successfully exploited this vulnerability could ascertain access tokens used to 
authenticate the current user on a targeted Microsoft online service.
