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

Published: September 14, 2010 | Updated: September 22, 2010

Version: 1.1

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.

Where are the file information details? 
Refer to the reference tables in the Security Update Deployment section for the location of the file information details.

Are Outlook Express, Windows Mail, or Windows Live Mail affected by the vulnerability described in this bulletin? 
No, Outlook Express, Windows Mail, and Windows Live Mail are not affected by the vulnerability described in this bulletin. These online communication tools for use with Windows are not related to Microsoft Outlook.

Why is this security update rated Critical for Outlook 2002 but rated Important for Outlook 2003 and Outlook 2007? 
This vulnerability affects Microsoft Outlook when connected to an Exchange server with Online Mode; however, by default, Microsoft Outlook 2003 and Microsoft Outlook 2007 connect to an Exchange Server with Cached Exchange Mode. This mitigating factor reduces the vulnerability from Critical to Important for Outlook 2003 and Outlook 2007 because these versions are not affected in a default configuration. Cached Exchange Mode is not available in Microsoft Outlook 2002.

I connect to multiple mail servers. Is my configuration of Outlook affected by the vulnerability? 
Only configurations that are connected to an Exchange server with Online Mode are affected by the vulnerability. Configurations where Outlook uses POP or IMAP mail servers only are not affected by this vulnerability. The following table summarizes these affected configurations.

Affected Configurations 

Exchange Online ModeCached Exchange ModePOP IMAP
Microsoft Outlook 2002 Service Pack 3AffectedNot applicableNot affectedNot affected
Microsoft Outlook 2003 Service Pack 3AffectedNot affectedNot affectedNot affected
Microsoft Outlook 2007 Service Pack 2AffectedNot affectedNot affectedNot affected

I'm running Outlook in a non-affected configuration. Will I still be offered the update? 
Yes. Regardless of configuration, if you are running an affected version of Microsoft Outlook, the update will be offered.

How are Microsoft Office standalone programs affected by the vulnerability? 
A Microsoft Office standalone program is affected with the same severity rating as the corresponding component in a Microsoft Office Suite. For example, a standalone installation of Microsoft Outlook is affected with the same severity rating as an installation of Microsoft Outlook that was delivered with a Microsoft Office Suite.

The Microsoft Office component discussed in this article is part of the Microsoft Office Suite that I have installed on my system; however, I did not choose to install this specific component. Will I be offered this update? 
Yes, if the component discussed in this bulletin was delivered with the version of the Microsoft Office Suite installed on your system, the system will be offered updates for it whether the component is installed or not. The detection logic used to scan for affected systems is designed to check for updates for all components that were delivered with the particular Microsoft Office Suite and to offer the updates to a system. Users who choose not to apply an update for a component that is not installed, but is delivered with their version of the Microsoft Office Suite, will not increase the security risk of that system. On the other hand, users who do choose to install the update will not have a negative impact on the security or performance of a system.

Does the offer to update a non-vulnerable version of Microsoft Office constitute an issue in the Microsoft update mechanism? 
No, the update mechanism is functioning correctly in that it detects a lower version of the files on the system than in the update package and thus, offers the update.

I am using an older release of the software discussed in this security bulletin. What should I do? 
The affected software listed in this bulletin have been tested to determine which releases are affected. Other releases are past their support life cycle. For more information about the product lifecycle, visit the Microsoft Support Lifecycle Web site.

It should be a priority for customers who have older releases of the software to migrate to supported releases to prevent potential exposure to vulnerabilities. To determine the support lifecycle for your software release, see Select a Product for Lifecycle Information.

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.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2010-2728.

Mitigating Factors for Heap Based Buffer Overflow in Outlook Vulnerability - CVE-2010-2728

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • 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.
  • By default, Microsoft Outlook 2003 and Microsoft Outlook 2007 connect to an Exchange server with Cached Exchange Mode. Outlook is not affected by the vulnerability when retrieving data from an Exchange server with Cached Exchange Mode. Cached Exchange Mode is not available in Microsoft Outlook 2002.
  • A Microsoft Outlook client is not affected by the vulnerability when not connected to an Exchange server, such as when connected to a POP or IMAP server only.

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

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

  • Read e-mails in plain text

    To help protect yourself from the e-mail attack vector, read e-mail messages in plain text format.

    Microsoft Outlook 2002 users who have applied Microsoft Office XP Service Pack 1 or a later version can enable this setting and view in plain text only those e-mail messages that are not digitally signed or e-mail messages that are not encrypted.

    Digitally signed e-mail messages or encrypted e-mail messages are not affected by the setting and may be read in their original formats. For more information about how to enable this setting in Outlook 2002, see Microsoft Knowledge Base Article 307594.

    Impact of workaround. E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Additionally:

    • The changes are applied to the preview pane and to open messages.
    • Pictures become attachments so that they are not lost.
    • Because the message is still in Rich Text or HTML format in the store, the object model (custom code solutions) may behave unexpectedly.

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

What is the scope of the vulnerability? 
This is a remote code execution 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.

What causes the vulnerability? 
Microsoft Outlook does not properly parse a specially crafted e-mail message.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could run arbitrary code as the logged-on user. If a user is logged on with administrative user rights, an attacker could take complete control of the 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.

How could an attacker exploit the vulnerability? 
Exploitation of this vulnerability requires that a user open or preview a specially crafted e-mail message with an affected version of Microsoft Outlook that is connected to an Exchange Server in Online Mode.

In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially crafted e-mail message to the user and convincing the user to preview or open the e-mail.

    To verify that a security update has been applied to an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. See the section, Detection and Deployment Tools and Guidance, earlier in this bulletin for more information.

  • File Version Verification

    Because there are several editions of Microsoft Windows, the following steps may be different on your system. If they are, see your product documentation to complete these steps.

    1. Click Start and then enter an update file name in the Start Search box.
    2. When the file appears under Programs, right-click the file name and click Properties.
    3. On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
    4. You can also click the Details tab and compare information, such as file version and date modified, with the file information tables provided in the bulletin KB article.
    5. Finally, you can also click the Previous Versions tab and compare file information for the previous version of the file with the file information for the new, or updated, version of the file.
