Microsoft Security Bulletin MS10-064 - Critical

Vulnerability in Microsoft Outlook Could Allow Remote Code Execution (2315011)

Version: 1.0

General Information

Executive Summary

This security update resolves a privately reported vulnerability. The 
vulnerability could allow remote code execution if a user opened or previewed 
a specially crafted e-mail message using an affected version of Microsoft 
Outlook that is connected to an Exchange server with Online Mode. An attacker 
who successfully exploited this vulnerability 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 
Outlook 2002 and is rated Important for all supported editions of Microsoft 
Outlook 2003 and Microsoft Outlook 2007. For more information, see the 
subsection, Affected and Non-Affected Software, in this section.

This security update addresses the vulnerability by correcting the way that 
Microsoft Outlook parses content in a specially crafted e-mail message. For 
more information about the vulnerability, see the Frequently Asked Questions 
(FAQ) subsection for the specific vulnerability entry under the next section, 
Vulnerability Information.

Vulnerability Information

Heap Based Buffer Overflow in Outlook Vulnerability - CVE-2010-2728

A remote code execution vulnerability exists in the way that Microsoft 
Outlook parses content in a specially crafted e-mail message. This 
vulnerability exists only in configurations where Outlook connects to an 
Exchange Server in Online Mode. Configurations where Outlook connects to an 
Exchange Server in the Cached Exchange Mode are not affected. In addition, 
configurations where Outlook uses POP or IMAP mail servers only are not 
affected by this vulnerability. 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.
