Vulnerabilities in Microsoft Exchange Server WebReady Document Viewing Could Allow Remote Code Execution (2740358)
Published: August 14, 2012 | Updated: November 20, 2012
Version: 2.2
General Information
Executive Summary
This security update resolves publicly disclosed vulnerabilities in Microsoft Exchange Server WebReady Document Viewing. The vulnerabilities could allow remote code execution in the security context of the transcoding service on the Exchange server if a user previews a specially crafted file using Outlook Web App (OWA). The transcoding service in Exchange that is used for WebReady Document Viewing is running in the LocalService account. The LocalService account has minimum privileges on the local computer and presents anonymous credentials on the network.
This security update is rated Critical for all supported editions of Microsoft Exchange Server 2007 and Microsoft Exchange Server 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by updating the affected Oracle Outside In libraries to a non-vulnerable version. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerabilities entry under the next section, Vulnerability Information.
This security update also addresses the vulnerabilities first described in Microsoft Security Advisory 2737111 for affected editions of Microsoft Exchange Server.
Recommendation. Customers can configure automatic updating to check online for updates from Microsoft Update by using the Microsoft Update service. Customers who have automatic updating enabled and configured to check online for updates from Microsoft Update typically will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates from Microsoft Update and install this update manually. For information about specific configuration options in automatic updating in supported editions of Windows XP and Windows Server 2003, see Microsoft Knowledge Base Article 294871. For information about automatic updating in supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, see Understanding Windows automatic updating.
For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.

Frequently Asked Questions (FAQ) Related to This Security Update
I have already successfully installed the original KB2734323, KB2743248, or KB2706690 updates. Do I need to apply the rereleased update packages (KB2756497, KB2756496, or KB2756485) released on October 9, 2012?
Yes. In all cases, customers need to apply the rereleased update packages.
Note Applicability for these rereleased update packages is not dependent on the version of Microsoft Windows on which Microsoft Exchange is installed.
Why was this bulletin revised on October 9, 2012?
Microsoft revised this bulletin to offer the rerelease of updates for Microsoft Exchange Server 2007 Service Pack 3 (KB2756497), Microsoft Exchange Server 2010 Service Pack 1 (KB2756496), and Microsoft Exchange Server 2010 Service Pack 2 (KB2756485) to address an issue involving specific digital certificates that were generated by Microsoft without proper timestamp attributes.

Verifying that the Update Has Been Applied
Microsoft Baseline Security Analyzer
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.- Click Start and then enter an update file name in the Start Search box.
- When the file appears under Programs, right-click the file name and click Properties.
- On the General tab, compare the file size with the file information tables provided in the bulletin KB article.
Note Depending on the edition of the operating system, or the programs that are installed on your system, some files that are listed in the file information table may not be installed. - 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.
Note Attributes other than the file version may change during installation. Comparing other file attributes to the information in the file information table is not a supported method of verifying that the update has been applied. Also, in certain cases, files may be renamed during installation. If the file or version information is not present, use one of the other available methods to verify update installation. - 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.
Registry Key Verification
You may also be able to verify the files that this security update has installed by reviewing the registry keys listed in the Reference Table in this section.These registry keys may not contain a complete list of installed files. Also, these registry keys may not be created correctly when an administrator or an OEM integrates or slipstreams this security update into the Windows installation source files.
