Microsoft Security Bulletin MS10-087 - Critical

Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2423930)

Version: 1.0

General Information

Executive Summary

This security update resolves one publicly disclosed vulnerability and four 
privately reported vulnerabilities in Microsoft Office. The most severe 
vulnerability could allow remote code execution if a user opens or previews a 
specially crafted RTF e-mail message. An attacker who successfully exploited 
any of these vulnerabilities could gain the same user rights as the local 
user. 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.

This security update is rated Critical for all supported editions of Microsoft 
Office 2007 and Microsoft Office 2010. This security update is also rated 
Important for all supported editions of Microsoft Office XP, Microsoft Office 
2003, Microsoft Office 2004 for Mac, Microsoft Office 2008 for Mac, and 
Microsoft Office for Mac 2011; and Open XML File Format Converter for Mac. 
For more information, see the subsection, Affected and Non-Affected Software,

Vulnerability Information

RTF Stack Buffer Overflow Vulnerability - CVE-2010-3333

A remote code execution vulnerability exists in the way that affected 
Microsoft Office software parses specially crafted Rich Text Format (RTF) 
formatted data. 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.

Office Art Drawing Records Vulnerability - CVE-2010-3334

A remote code execution vulnerability exists in the way that Microsoft 
Office software parses specially crafted Office 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.

Drawing Exception Handling Vulnerability - CVE-2010-3335

A remote code execution vulnerability exists in the way that Microsoft 
Office software parses specially crafted Office 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.

MSO Large SPID Read AV Vulnerability - CVE-2010-3336

A remote code execution vulnerability exists in the way that Microsoft 
Office software parses specially crafted Office 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.

Insecure Library Loading Vulnerability - CVE-2010-3337

A remote code execution vulnerability exists in the way that Microsoft 
Office handles the loading of 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
