Microsoft Security Bulletin MS08-016 - Critical
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (949030)
Published: March 11, 2008 | Updated: April 30, 2008
Version: 2.1
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities in Microsoft Office that could allow remote code execution if a user opens a malformed Office file. 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.
This security update is rated Critical for supported editions of Microsoft Office 2000 and rated Important for supported editions of Microsoft Office XP, Microsoft Office 2003 Service Pack 2, Microsoft Office Excel Viewer 2003 and Microsoft Office Excel Viewer 2003 Service Pack 3, Microsoft Office Word Viewer 2003 and Microsoft Office Word Viewer 2003 Service Pack 3, and Microsoft Office 2004 for Mac. For more information, see the subsection, Affected and Non-Affected Software, in this section.
This security update addresses these vulnerabilities by modifying the way that Microsoft Office allocates memory. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

File Version Verification
Because there are several versions and editions of Microsoft Office, the following steps may be different on your system. If they are, see your product documentation to complete these steps.
- Click Start, and then click Search.
- In the Search Results pane, click All files and folders under Search Companion.
- In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
- In the list of files, right-click a file name from the appropriate file information table, and then click Properties.
Note Depending on the version of the operating system or programs installed, some of the files that are listed in the file information table may not be installed. - On the Version tab, determine the version of the file that is installed on your system by comparing it to the version that is documented in the appropriate file information table.
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.
