Frequently Asked Questions (FAQ) Related to This Security Update
Why was this bulletin revised on August 13, 2008?
Microsoft revised this bulletin to clarify that the update for Microsoft Office Project 2002 Service Pack 1 is the same as the update for Microsoft Office XP Service Pack 3 in the Affected Software table. Because the update is the same, Project 2002 does not have a separate subsection in the section, Security Update Deployment. This is a bulletin change only. Customers who have already successfully installed this update do not have to reinstall.
I do not have all of the affected software installed, but I do have other Microsoft Office applications installed. Why am I being offered the security update?
The vulnerabilities described in this security update exist within Microsoft Office but could not be exploited using one of the applications listed in the Non-Affected Software table. The Microsoft Office applications listed in the Non-Affected Software table use some of the same files as the applications listed in the Affected Software table to which the security update applies. We recommend installing the update to prevent the security update from being offered again.
I use Microsoft Office 2003 Service Pack 2. Are any additional security features included in this update?
Yes, as part of the servicing model for Microsoft Office 2003, when users of Microsoft Office 2003 Service Pack 2 install this update, their systems will be upgraded to security functionality that was initially released with Microsoft Office 2003 Service Pack 3. All updates released after January 1, 2008 for Microsoft Office 2003 Service Pack 2 will include these security features, which were introduced in Microsoft Office 2003 Service Pack 3. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to the environment and configuration of their systems. For more information on this issue, please see Microsoft Knowledge Base Article 951646.
Where are the file information details?
The file information details can be found in Microsoft Knowledge Base Article 924090.
Why does this update address several reported security vulnerabilities?
This update contains support for several vulnerabilities because the modifications that are required to address these issues are located in related files. Instead of having to install several updates that are almost the same, customers need to install this update only.
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. To determine the support life cycle for your software release, visit Microsoft Support Lifecycle.
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. For more information about the Windows Product Lifecycle, visit Microsoft Support Lifecycle. For more information about the extended security update support period for these software versions or editions, visit Microsoft Product Support Services.
Customers who require custom support for older releases must contact their Microsoft account team representative, their Technical Account Manager, or the appropriate Microsoft partner representative for custom support options. Customers without an Alliance, Premier, or Authorized Contract can contact their local Microsoft sales office. For contact information, visit Microsoft Worldwide Information, select the country, and then click Go to see a list of telephone numbers. When you call, ask to speak with the local Premier Support sales manager. For more information, see the Windows Operating System Product Support Lifecycle FAQ.
I use Microsoft Office 2003 Service Pack 3. Why am I still being offered this update?
Microsoft Office 2003 Service Pack 3 is not impacted by the security vulnerabilities documented in this bulletin. However, users will still be offered this update because the files included with the update have a higher version number than the files that are currently on your 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.
What is included in the Microsoft Office update that causes the higher version of the update files?
The update files include changes to support stability changes in Microsoft Office and additional changes to support corporate environment changes. We have thoroughly tested this update, but as with all updates, we recommend that users perform testing appropriate to their environment and configurations of their systems.

Microsoft Malformed EPS Filter Vulnerability - CVE-2008-3019
A remote code execution vulnerability exists in the way that a Microsoft Office filter handles a malformed graphics image. An attacker could exploit the vulnerability by constructing a specially crafted Encapsulated PostScript (EPS) file that could allow remote code execution if a user opened the file with a Microsoft Office application. Such a specially crafted file might be included as an e-mail attachment, or hosted on a malicious or compromised Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, significant user interaction is required to exploit this vulnerability.
To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2008-3019.
Mitigating Factors for Microsoft Malformed EPS Filter Vulnerability - CVE-2008-3019
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:
- This vulnerability could not be exploited automatically through a Web-based attack scenario. An attacker would have to host a Web site that contains an Office file containing a specially crafted EPS image that is used to attempt to exploit this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site, and then convince the user to open the file in an affected Microsoft Office application.
- 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.
- The vulnerability could be exploited by an attacker who convinced a user to open a specially crafted file. There is no way for an attacker to force a user to open a specially crafted file. Additionally, when Microsoft Word is being used as the HTML e-mail editor in Outlook, a user would need to reply to or forward a malicious e-mail message in order for this vulnerability to be exploited.
- Users who have installed and are using the Office Document Open Confirmation Tool for Office 2000 will be prompted with Open, Save, or Cancel before opening a document. The features of the Office Document Open Confirmation Tool are incorporated in Office XP and Office 2003.

FAQ for Microsoft PICT Filter Parsing Vulnerability - CVE-2008-3021
What is the scope of the vulnerability?
A remote code execution vulnerability exists in Microsoft Office and could be exploited when a specially crafted PICT-format image file is opened by any of the affected Microsoft Office applications. Such a file might be included in an e-mail attachment or hosted on a malicious Web site. Viewing or previewing the specially crafted PICT-format image file in Outlook could not lead to exploitation of this vulnerability. An attacker could exploit this vulnerability only by constructing a specially crafted image file and convincing a user to open the file with one of the affected applications.
If the user is logged on with administrative user rights, 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 the same user rights as the logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.
What causes the vulnerability?
When Microsoft Office opens a specially crafted PICT image file, it may corrupt system memory in such a way that an attacker could execute arbitrary code.
What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could take complete control of the affected system.
How could an attacker exploit the vulnerability?
This vulnerability could not be exploited automatically through a Web-based attack scenario. An attacker would have to host a Web site that contains an Office file that is used to attempt to exploit this vulnerability. An attacker would have no way to force users to visit a malicious Web site. Instead, an attacker would have to convince them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site, and then convince the user to open the file in an affected Microsoft Office application.
In an e-mail attack scenario, an attacker could exploit the vulnerability by sending a specially-crafted file to the user and by persuading the user to open the file. Additionally, when Microsoft Word is being used as the HTML e-mail editor in Outlook, a user would need to reply to or forward a malicious e-mail message sent to them in order for this vulnerability to be exploited.
What systems are primarily at risk from the vulnerability?
Workstations and terminal servers that have Microsoft Office installed are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.
What does the update do?
This update removes the vulnerability by modifying the way that Microsoft Office parses the length of a PICT-format image file before passing the file to the allocated buffer.
When this security bulletin was issued, had this vulnerability been publicly disclosed?
No. Microsoft received information about this vulnerability through responsible disclosure. Microsoft had not received any information to indicate that this vulnerability had been publicly disclosed when this security bulletin was originally issued.
When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
