IntroductionMicrosoft® Office 2003 Service Pack 3 (SP3) is the culmination of several years of improvements to the product suite. In addition to bringing together previously released updates into one package, Office 2003 SP3 also addresses a range of user experience issues.

For employees and home users, Office 2003 SP3 improves the performance and simplifies the use of applications they rely upon most. Office 2003 SP3 makes it easier to work with the Windows Vista® operating system, exchange files with people who use the 2007 Microsoft Office system, and interact with servers in the 2007 release. And by addressing more customer requests, Office 2003 SP3 minimizes issues that previously caused distractions.

For businesses, Office 2003 SP3 is a crucial update that addresses security issues surrounding legacy file formats and add-ins using the Microsoft component object model (COM) and privacy concerns regarding hidden metadata. The service pack also provides IT administrators with more tools to protect the company’s IT and intellectual assets. It strengthens security by closing off frequently exploited methods of attack, incorporating security enhancements developed as part of the 2007 release, and giving IT administrators greater control over user behavior.

Business ConsiderationsAlthough home and office users will benefit from installing Microsoft® Office 2003 Service Pack 3 (SP3) as soon as possible, many businesses may hesitate because of the concerns regarding deployment and compatibility with existing systems and applications. This section addresses major business considerations and provides positive reasons for immediate deployment.

Increased SecurityCompanies that have not yet upgraded to the 2007 Microsoft Office system can still benefit from many of the major security improvements in that version by deploying Office 2003 SP3, which incorporates many security enhancements included in the 2007 release. These improvements make Office 2003 SP3 an essential upgrade, especially to mitigate current and emerging security concerns.

Office 2003 SP3 helps businesses defend themselves against external threats, such as malicious software infections, by closing off avenues of attack:

Office 2003 SP3 now automatically tests add-ins using the Microsoft component object model (COM) and ActiveX® controls and blocks a subset of insecure components.

Office 2003 SP3 provides IT administrators with more powerful policy controls regarding COM objects.

Microsoft Office Excel® 2003 now allows users to determine which macros written in Microsoft Visual Basic® for Applications they will allow to run in Microsoft Excel 5.0/95 Workbook format-based files.

Microsoft Office Outlook® 2003 now automatically blocks .gadget files, which contain executable code.

Office 2003 SP3 also empowers companies to comply with government regulations and stem leaks of confidential information, whether inadvertent or intentional. In April 2007, Forrester Research reported that companies paid between U.S.$90 and U.S.$305 for each record that was leaked, stolen, or lost.1 Together, with strong policies and user education, Office 2003 SP3 helps companies prevent embarrassing and costly data security breaches. For example, Microsoft Office Word 2003 no longer uses the Fast Save feature, which might retain confidential information that could be extracted after a document is sent outside the company.

Protection from Social Engineering AttacksOffice 2003 SP3 includes greater protection from attacks that use “social engineering” techniques to spread malicious software and steal important corporate information. Social engineering attacks are a growing threat to companies. The Microsoft Windows Malicious Software Removal Tool (MSRT), freely distributed to at least 270 million unique computers since its release in 2005, provides Microsoft with insight into how malicious software is spread. Using data from MSRT, the Microsoft Antimalware Team reported in November 2006 that 35 percent of all machine infections resulted from social engineering attacks.2

Microsoft Office 2003 Service Pack 3 White Paper 1

Stymied by filters and firewalls that block automated attacks, hackers are shifting their focus to the applications, especially common desktop software. These attacks depend largely on social engineering—convincing a user inside the network to unwittingly install malicious software or otherwise take actions that compromise security. Recognizing this trend, Microsoft focused on making applications in the 2007 Microsoft Office system more resilient against social engineering attacks. This was accomplished by building more automated safeguards into the product while also simplifying user-driven security decisions.

After evaluating the success of these improvements, it was clear that many could increase protection in the 2003 Office release as well. Office 2003 SP3 is the vehicle for delivering this increased protection. One of the enhanced security measures provided with Office 2003 SP3 is the Microsoft Office Isolated Conversion Environment (MOICE). This tool automatically runs documents through a conversion and scrubbing process to remove malicious content, helping to protect users against malicious code concealed within rigged documents. Office 2003 SP3 also gives IT administrators methods of controlling what types of files users can download and open. Having more control allows IT administrators to quickly adjust what file types and behaviors are permitted in response to constantly evolving attacks.

Increased ProductivityOffice 2003 SP3 also offers significant improvements to the user experience, which translate into increased productivity, especially for companies that are transitioning to the Windows Vista® operating system and the 2007 Microsoft Office system. For instance, Office 2003 SP3 makes it easier for employees to view and work with newer files created by their co-workers and business contacts using Microsoft Office programs. Improvements in compatibility with Windows Vista and the 2007 release include:

When running in Windows Vista, Microsoft Office OneNote® 2003 now reports the correct hyperlink address when clipping from a multiple-tab browser session on Windows® Internet Explorer® 7.

Microsoft Office Project 2003 reads files created in Office Project 2007.

In addition to smoothing compatibility issues, Office 2003 SP3 also improves productivity by resolving minor distractions, such as:

Microsoft Office Access 2003 no longer causes the computer screen to flicker when users move the mouse cursor over pages of a tab control.

Microsoft Office PowerPoint 2003 now allows users to update a linked Object Linking and Embedding (OLE) object, such as a linked external picture, without error.

Excel 2003 now displays security warnings when opening a large spreadsheet with macros over a slow network share, allowing users to decide whether to run macros or not.

Word 2003 users can copy and paste text from a Web e-mail account—such as Windows Live™ Hotmail®, or Yahoo! Mail—in Internet Explorer 7, without causing Word 2003 to crash.

Minor Impact on Existing SystemsPerhaps of most concern to some companies is how Office 2003 SP3 will impact their existing systems, especially those that use custom tie-ins to Microsoft Office programs. Microsoft has rigorously tested Office 2003 SP3 with major business software packages, including third-party products from Hyperion and SAP, and identified no major compatibility issues. However, as a best practice, organizations should conduct compatibility tests with critical systems and solutions before deploying Office 2003 SP3 across the organization. Other changes to the 2003 Office release that might adversely affect systems and workflows are referenced here in this white paper and documented more thoroughly in referenced Microsoft Knowledge Base (KB) articles. The most noticeable of these changes:

The functionality of COM add-ins and ActiveX controls may be reduced or blocked if the component uses insecure interface methods. Office 2003 SP3 automatically tests all COM components and limits potentially insecure functions. Although most components will pass this automatic test, Microsoft provides guidance on how IT administrators can update their COM add-ins and ActiveX controls to comply.

Legacy file formats created using Microsoft Office programs are disabled by default. This increases security because hackers can more easily find vulnerabilities in the older formats. IT administrators can change the settings to allow specific document formats, if needed.

Microsoft Office 2003 Service Pack 3 White Paper 6

Security ImprovementsMicrosoft® Office 2003 Service Pack 3 (SP3) offers important security enhancements for both consumers and businesses. Office 2003 SP3 hardens applications against attack by providing protection against corrupted documents or tampered file formats that might contain malware. The new update also helps IT administrators enforce corporate IT policies by controlling what types of files users can open. Finally, Office 2003 SP3 helps companies prevent embarrassing data security breaches by completely erasing hidden metadata from scrubbed documents.

This section summarizes the most important security improvements included in Office 2003 SP3 and references associated Microsoft Knowledge Base (KB) articles.

Microsoft Office Isolated Conversion Environment and File BlockOffice 2003 SP3 includes two important security tools that greatly reduce the threat of malware concealed within Microsoft Office documents. Released separately in Spring 2007, both tools were developed using technology in the 2007 Microsoft Office system but were developed largely to benefit Microsoft Office Excel® 2003, Microsoft Office PowerPoint® 2003, and Microsoft Office Word 2003.

Microsoft Office Isolated Conversion Environment (MOICE) allows users to open Microsoft Office documents from unknown senders with relative safety. MOICE uses the converters in the Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats to convert binary format files into the newer Office Open XML format. The conversion process removes malicious content within corrupted or tampered documents and has successfully remedied all issues to date. MOICE conducts these cleansings in a restricted process, thereby protecting the underlying system in the event that any code tries to execute during the conversion process.

File Block complements MOICE by allowing IT administrators to temporarily prevent certain file formats from opening through registry or group policy. This provides companies with the flexibility needed to quickly respond to evolving threats without unduly limiting productivity.

There are some important considerations for MOICE and File Block, so please refer to these links for more information: KB Article 935865 and Microsoft Security Advisory 937696.

COM Add-Ins and ActiveX ControlsAlthough Microsoft component object model (COM) add-ins and ActiveX® controls in Microsoft Office documents offer rich, customized functionality, they are also a potential security risk without rigorous IT policies and tools in place. At worst, Microsoft Office documents with these components could harbor malicious code that runs automatically once the document is opened.

Office 2003 SP3 further strengthens the 2003 Microsoft Office release against these scenarios with a new automatic test for COM add-ins and ActiveX controls to ensure they are not written using a potentially insecure QueryInterface() method. This automatic test is run when programs in the 2003 Microsoft Office release are started and poses no problem for components with properly addressed interface code. For more information, read KB Article 938814.

In addition, Office 2003 SP3 allows administrators and users to set registry settings to control the behavior of COM add-ins. To read more, see KB Article 938815.

Microsoft Office 2003 Service Pack 3 White Paper 7

Access 2003When employing macros that require a password, Microsoft Office Access 2003 now alerts users that the password is stored in clear text and not encrypted.

Excel 2003Office 2003 SP3 updates the default security settings for Microsoft Visual Basic® for Applications macros in Microsoft Excel® 5.0/95 Workbook files. These files may contain an older Microsoft Excel 4.0 macro type that cannot be disabled or signed. If the workbook files contain these macros, they will not open in Excel 2003 when macro security levels are set to High or Very High; if the macro security level is set to Medium, the user will be prompted to enable or disable the macros. This change provides users with more control to determine which macros will run and protects against attacks that take advantage of weaknesses in the older file format. For more information, read KB Article 938806.

Outlook 2003Microsoft Office Outlook® 2003 now blocks .gadget files that are sent as e-mail attachments because they contain executable code—possibly a malicious software payload. If the user needs a .gadget file from someone, they can request the file be uploaded to a file share or compressed using a file compression utility before sent through e-mail. For more information, read KB Article 938811.

Visio 2003Microsoft Office Visio® 2003 now allows IT administrators to disable AutoCAD file format (.dwg) files to improve security. Once disabled, AutoCAD Drawing options will be removed from Open and Save As dialog boxes. Files created in Visio that contain CAD objects will not display those objects. For more information, read KB Article 938803.

Word 2003To ensure confidential data is not inadvertently passed on in metadata, Office 2003 SP3 disables the Fast Save feature. The Allow Fast Saves check box will continue to appear in the Save Options dialog, but it will not be functional.

While the Fast Save feature speeds up the document-saving process by saving only the changes made to a document, the saved document may contain metadata, such as comments, erased text, previous versions, and authorship. Disabling Fast Save ensures that confidential data is protected against improper disclosure. For more information, read KB Article 938808.
