General Information

Executive Summary:

This update resolves two newly discovered, privately reported vulnerabilities. Each vulnerability is documented in its own subsection in the "Vulnerability Details" section of this bulletin.

If a 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 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.

We recommend that customers apply the update immediately.

Note The severity ratings for non-x86 operating system versions map to the x86 operating systems versions as follows:

  • The Microsoft Windows XP Professional x64 Edition severity rating is the same as the Windows XP Service Pack 2 severity rating.
  • The Microsoft Windows Server 2003 R2 Systems severity rating is the same as the Windows Server 2003 severity rating.
  • The Microsoft Windows Server 2003 for Itanium-based Systems severity rating is the same as the Windows Server 2003 severity rating.
  • The Microsoft Windows Server 2003 with SP1 for Itanium-based Systems severity rating is the same as the Windows Server 2003 Service Pack 1 severity rating.
  • The Microsoft Windows Server 2003 x64 Edition severity rating is the same as the Windows Server 2003 Service Pack 1 severity rating.
  • The Microsoft Office 2003 Service Pack 1 or Service Pack 2 severity rating is the same as the Windows operating system version that they resides on.
  • The Microsoft XML Core Services 4.0 severity rating is the same as the Windows operating system version that it resides on.
  • The Microsoft XML Core Services 6.0 severity rating is the same as the Windows operating system version that it resides on.

For the Office 2003 update, I am updating the administrative installation points and I noticed that there are two .msp’s. Why?
Limitations in our security update detection logic necessitate us having two separate updates. This is because the file being updated, mso.dll, ships in so many products that if we used a single .MSP to target them all, the detection logic in the MSP would be too large for our detection tools to consume. We are actively working on resolving this limitation.

For the Office 2003 update, the administrative installation points lists msxml5.msp and pvmsxm5.msp. Do I need to install both packages?
Yes, the msxml5.msp targets most of the Office products, such as Word and Excel. The pvmsxm5.msp targets additional Office products, such as Visio, Project and OneNote. In order to be secure you will need to install both packages

Why did Microsoft reissue this bulletin on October 19, 2006?
This bulletin has been re-released to re-offer the security update to customers with Windows 2000 Service Pack 4. The security update previously did not correctly set the kill bit for Microsoft XML Parser 2.6. Additional information has also been included for customers wishing to remove the security update for Microsoft XML Core Services 4.0 and Microsoft XML Core Services 6.0.

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 can install only this update.

What version of Microsoft XML Core Services is installed on my system?
For information about the different Microsoft XML Core Services versions that are available and the products that install them, see Microsoft Knowledge Base Article 269238.

Does this update contain any security-related changes to functionality?
Yes. Besides the changes that are listed in the "Vulnerability Details" section of this bulletin, this update sets a kill bit for a list of Class Identifiers (CLSIDs) for Microsoft XML Parser 2.6, which will remove support in Microsoft Internet Explorer.

The CLSIDs and corresponding files where the Microsoft XML Parser 2.6 functionality is contained are as follows.

Microsoft XML Core Services Vulnerability - CVE-2006-4685:

A vulnerability exists in Microsoft XML Core Services that could allow for information disclosure because the XMLHTTP ActiveX control incorrectly interprets an HTTP server-side redirect. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could potentially lead to information disclosure if a user visited that page or clicked a link in a specially crafted e-mail message. An attacker who successfully exploited this vulnerability could access content from another domain retrieved using the credentials of the user browsing the Web at the client. In addition, compromised Web sites and Web sites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. However, user interaction is required to exploit this vulnerability.

Mitigating Factors for Microsoft XML Core Services Vulnerability - CVE-2006-4685:

  • In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit the page. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or instant messenger message that takes users to the attacker's Web site.
  • By default, Internet Explorer on Windows Server 2003 runs in a restricted mode that is known as Enhanced Security Configuration. This mode mitigates this vulnerability from sites that are not explicitly allowed to run script and ActiveX controls. See the FAQ section of this security update for more information about Internet Explorer Enhanced Security Configuration.

Workarounds for Microsoft XML Core Services Vulnerability - CVE-2006-4685:

  • Set Internet and Local intranet security zone settings to “High” to prompt before running ActiveX controls and active scripting in the Internet zone and in the Local intranet zone.

    You can help protect against this vulnerability by changing your settings for the Internet security zone to prompt before running ActiveX controls and active scripting. You can do this by setting your browser security to High.

    To raise the browsing security level in Microsoft Internet Explorer:

    1. On the Internet Explorer Tools menu, click Internet Options.
    2. In the Internet Options dialog box, click the Security tab, and then click the Internet icon.
    3. Under Security level for this zone, move the slider to High. This sets the security level for all Web sites you visit to High.

    Note If no slider is visible, click Default Level, and then move the slider to High.

    Note Setting the level to High may cause some Web sites to work incorrectly. If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the high security setting.

    Alternatively, you can change you settings to prompt before running ActiveX controls only by following these steps:

    1. In Internet Explorer, click Internet Options on the Tools menu.
    2. Click the Security tab.
    3. Click Internet, and then click Custom Level.
    4. Under Settings, in the ActiveX controls and plug-ins section, under Run ActiveX controls and plug-ins, click Prompt.
    5. In the Scripting section, under Active Scripting, click Prompt, and then click OK.
    6. Click Local intranet, and then click Custom Level.
    7. Under Settings, in the ActiveX controls and plug-ins section, under Run ActiveX controls and plug-ins, click Prompt.
    8. In the Scripting section, under Active Scripting, click Prompt.
    9. Click OK two times to return to Internet Explorer.

    Impact of Workaround: There are side effects to prompting before running ActiveX controls. Many Web sites that are on the Internet or on an intranet use ActiveX to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX controls to provide menus, ordering forms, or even account statements. Prompting before running ActiveX controls is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click Yes to run ActiveX controls. If you do not want to be prompted for all these sites, use the "Restrict Web sites to only your trusted Web sites" workaround.

FAQ for Microsoft XML Core Services Vulnerability - CVE-2006-4685:

What is the scope of the vulnerability?
This is an information disclosure vulnerability. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could potentially lead to information disclosure if a user visited that page or clicked a link in a specially crafted e-mail message. An attacker who successfully exploited this vulnerability could access content from another domain retrieved using the credentials of the user browsing the Web at the client. However, user interaction is required to exploit this vulnerability.

What causes the vulnerability?
A flaw exists in how the XMLHTTP control applies IE security settings to a redirected data stream returned in response to a request for data from a Web site.

What is Microsoft XML Core Services (MSXML)?
Microsoft XML Core Services (MSXML) allows customers who use JScript, Visual Basic Scripting Edition (VBScript), and Microsoft Visual Studio 6.0 to build high-performance XML-based applications that provide a high degree of interoperability with other applications that adhere to the XML 1.0 standard. See the MSDN Web site for more information regarding MSXML.

What might an attacker use the vulnerability to do?
An attacker who successfully exploited this vulnerability could read cookies or other data from another security zone or domain in Internet Explorer.

Who could exploit the vulnerability?
An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site. This can also include Web sites that accept user-provided content or advertisements, Web sites that host user-provided content or advertisements, and compromised Web sites. These Web sites could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger request that takes users to the attacker's Web site. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.

What systems are primarily at risk from the vulnerability?
This vulnerability requires that a user is logged on and visits a Web site for any malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability. Systems that are not typically used to visit Web sites, such as most server systems, are at a reduced risk.

What is the Internet Explorer Enhanced Security Configuration?
Internet Explorer Enhanced Security Configuration is a group of preconfigured Internet Explorer settings that reduce the likelihood of a user or of an administrator downloading and running specially crafted Web content on a server. Internet Explorer Enhanced Security Configuration reduces this risk by modifying many security-related settings. This includes the settings on the Security tab and the Advanced tab in the Internet Options dialog box. Some of the important modifications include the following:

  • Security level for the Internet zone is set to High. This setting disables scripts, ActiveX controls, Microsoft Java Virtual Machine (MSJVM), and file downloads.
  • Automatic detection of intranet sites is disabled. This setting assigns all intranet Web sites and all Universal Naming Convention (UNC) paths that are not explicitly listed in the Local intranet zone to the Internet zone.
  • Install On Demand and non-Microsoft browser extensions are disabled. This setting prevents Web pages from automatically installing components and prevents non-Microsoft extensions from running.
  • Multimedia content is disabled. This setting prevents music, animations, and video clips from running.

For more information regarding Internet Explorer Enhanced Security Configuration, see the guide, Managing Internet Explorer Enhanced Security Configuration, at the following Web site.

What does the update do?
The update removes the vulnerability by correcting the behavior of XML Core Services. XML Core Services will now interpret a server-side redirect in the XMLHTTP control differently and abort properly in previously unhandled circumstances.

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.

XSLT Buffer Overrun Vulnerability - CVE-2006-4686:

A vulnerability exists in XSLT processing that could allow remote code execution on an affected system. An attacker could exploit the vulnerability by constructing a malicious Web page that could potentially allow remote code execution if a user visited that page. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Mitigating Factors for XSLT Buffer Overrun Vulnerability - CVE-2006-4686:

  • In a Web-based attack scenario, an attacker would have to host a Web site that contains a Web page that is used to exploit this vulnerability. An attacker would have no way to force users to visit that page. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or instant messenger message that takes users to the attacker's Web site.
  • 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.

Workarounds for XSLT Buffer Overrun Vulnerability - CVE-2006-4686:

We have not identified any workarounds for this vulnerability.

FAQ for XSLT Buffer Overrun Vulnerability - CVE-2006-4686:

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

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 frequently asked question, “Can I use the Microsoft Baseline Security Analyzer (MBSA) to determine whether this update is required?” in the section, Frequently Asked Questions (FAQ) Related to This Security Update, earlier in this bulletin.

  • File Version Verification

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

    1. Click Start, and then click Search.
    2. In the Search Results pane, click All files and folders under Search Companion.
    3. In the All or part of the file name box, type a file name from the appropriate file information table, and then click Search.
    4. 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.
    5. On the Version tab, determine the version of the file that is installed on your computer 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.

  1. Download the security update for Office 2003.
  2. Click Save this program to disk, and then click OK.
  3. Click Save.
  4. Using Windows Explorer, locate the folder that contains the saved file. Click Start, click Run, type the following command, and then click OK to extract the .msp file:

    [path\name of EXE file] /c /t:C:\AdminUpdate

    Note Double-clicking the .exe file does not extract the .msp file; it applies the update to the local computer. In order to update an administrative image, you must first extract the .msp file.
  5. Click Yes to accept the License Agreement.
  6. Click Yes if you are prompted to create the folder.
  7. If you are familiar with the procedure for updating your administrative installation, click Start, click Run, type the following command, and then click OK:

    msiexec /a Admin Path\MSI File /p C:\adminUpdate\MSP File SHORTFILENAMES=TRUE

    Note Admin Path is the path of your administrative installation point for your application (for example, C:\Office2003), MSI File is the .msi database package for the application (for example, Data1.msi), and MSP File is the name of the administrative update (for example, SHAREDff.msp).

    Note You can append /qb+ to the command line so that the Administrative Installation dialog box and the End User License Agreement dialog box do not appear.
  8. Click Next in the provided dialog box. Do not change your CD key, installation location, or company name in the provided dialog box.
  9. Click I accept the terms in the License Agreement, and then click Install.

At this point, your administrative installation point is updated. Next, you must update the workstations configurations that were originally installed from this administrative installation. To do this, please review the “Workstation Deployment Information” section. Any new installations that you run from this administrative installation point will include the update.

Warning Any workstation configuration that was originally installed from this administrative installation before you installed the update cannot use this administrative installation for actions such as repairing Office or adding new features until you complete the steps in the “Workstation Deployment Information” section.

Workstation Deployment Information

To deploy the update to the client workstations, click Start, click Run, type the following command, and then click OK:

Msiexec /I Admin Path\MSI File /qb REINSTALL=Feature List REINSTALLMODE=vomu

Note Admin Path is the path of your administrative installation point for your application (for example, C:\Office2003), MSI File is the .msi database package for the application (for example, Data1.msi), and Feature List is the list of feature names (case sensitive) that must be reinstalled for the update.
