Why are the command line installation switches different for Windows 2000 and Windows XP operating systems for this release when compared Internet Explorer Cumulative Security Update, MS04-025?
Starting with MS04-038 the packages for Windows 2000 and Windows XP Service Pack 1 are using a new installation technology, Update.exe. As a result the installation options are different than in previous releases. Also, as part of the change to the Update.exe installation technology the Knowledge Base Article number of this update will no longer be displayed in the Help, About window for Internet Explorer. For more information on the command line switches used for this release, please reference the Security Update Information section of this bulletin. More information on Update.exe is located on the following Microsoft Web site.

Why are there two versions of the Internet Explorer 6 Service Pack 1 update?
A separate package has been created for Internet Explore 6 Service Pack 1 when used on Windows NT Server Service Pack 6a, Windows 98, Windows 98SE, and Windows Me. This update uses the same installer technology as previous releases, Iexpress. For details on installing this security update on those operating systems please see the Security Update Information sections of this bulletin. For more information on Iexpress, please see Microsoft Knowledge Base Article 197147.

Can I use the Microsoft Baseline Security Analyzer (MBSA) to determine if this update is required?
Yes. MBSA will determine if this update is required. For more information about MBSA, visit the MBSA Web site.

Note After April 20, 2004, the Mssecure.xml file that is used by MBSA 1.1.1 and earlier versions is no longer being updated with new security bulletin data. Therefore, scans that are performed after that date with MBSA 1.1.1 or earlier will be incomplete. All users should upgrade to MBSA 1.2 because it provides more accurate security update detection and supports additional products. Users can download MBSA 1.2 from the MBSA Web site. For more information about MBSA support, visit the following Microsoft Baseline Security Analyzer 1.2 Q&A Web site.

Can I use Systems Management Server (SMS) to determine if this update is required?
As noted in the Affected Components section of this bulletin, this release includes two packages for Internet Explorer 6 SP1. One package is designed for Windows 2000 and Windows XP Service Pack 1. This package uses the Update.exe installation technology discussed above. The second package is designed for Windows NT, Windows 98, and Windows Me. MBSA is not able to determine which Internet Explorer 6 SP1 update is required for a specific Operating System. A package intended for SMS Deployment only has been created that contains both versions of the Internet Explorer 6 Service Pack 1 updates. When deployed with SMS, this package will detect the operating system and install the correct version of the update for that operating system. MBSA, when used with SMS, will instruct SMS administrators to deploy this SMS Deployment package. For more information on this update, please see Microsoft Knowledge Base Article 889410.

HTML Elements Vulnerability - CAN-2004-1050:

A remote code execution vulnerability exists in Internet Explorer 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 a malicious Web site. An attacker who successfully exploited this vulnerability could take complete control of an affected system.

Mitigating Factors for HTML Elements Vulnerability - CAN-2004-1050:

  • 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 a malicious Web site. Instead, an attacker would have to persuade them to visit the Web site, typically by getting them to click a link that takes them to the attacker's site.
  • An attacker who successfully exploited this vulnerability could gain the same privileges as the user. Users whose accounts are configured to have fewer privileges on the system would be at less risk than users who operate with administrative privileges.
  • By default, Outlook Express 6, Outlook 2002, and Outlook 2003 open HTML e-mail messages in the Restricted sites zone. Additionally, Outlook 98 and Outlook 2000 open HTML e-mail messages in the Restricted sites zone if the Outlook E-mail Security Update has been installed. Outlook Express 5.5 Service Pack 2 opens HTML e-mail in the Restricted sites zone if Microsoft Security Bulletin MS04-018 has been installed. The Restricted sites zone helps reduce attacks that could attempt to exploit this vulnerability.

    The risk of attack from the HTML e-mail vector can be significantly reduced if you meet all the following conditions:

    • Install the update that is included with Microsoft Security Bulletin MS03-040 or a later Cumulative Security Update for Internet Explorer.
    • Use Microsoft Outlook 98 and Outlook 2000 with the Microsoft Outlook E-mail Security Update installed
    • Use Microsoft Outlook Express 6 or later or Microsoft Outlook 2000 Service Pack 2 or later in their default configuration.
  • The following software is not affected by this vulnerability.
    • Internet Explorer 5.01 Service Pack 3
    • Internet Explorer 5.01 Service Pack 4
    • Internet Explorer 5.5 Service Pack 2 on Windows Millennium Edition (Me)
    • Internet Explorer 6 on Windows Server 2003
    • Internet Explorer 6 on Windows XP Service Pack 2

Workarounds for HTML Elements Vulnerability - CAN-2004-1050:

Microsoft has tested the following workarounds. While these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified below.

  • Install the Outlook E-mail Security Update if you are using Outlook 2000 SP1 or earlier.

    By default, Outlook Express 6, Outlook 2002, and Outlook 2003 open HTML e-mail messages in the Restricted sites zone. Additionally, Outlook 98 and Outlook 2000 open HTML e-mail messages in the Restricted sites zone if the Outlook E-mail Security Update has been applied.

    Customers who use any of these products could be at a reduced risk from an e-mail-borne attack that tries to exploit this vulnerability unless the user clicks a malicious link in the e-mail message.

FAQ for HTML Elements Vulnerability - CAN-2004-1050:

What is the scope of the vulnerability?
This is a remote code execution vulnerability. If a user is logged on with administrative privileges, an attacker who successfully exploited this vulnerability could take complete control of an affected system, including installing programs; viewing, changing, or deleting data; or creating new accounts that have full privileges. Users whose accounts are configured to have fewer privileges on the system would be at less risk than users who operate with administrative privileges.

What causes the vulnerability?
An unchecked buffer in Internet Explorer processing of certain HTML elements such as FRAME and IFRAME elements.

What are IFRAME elements?
Inline Floating Frames (IFRAME) is a technology that allows Web authors to have increased control of the design and interaction of their Web pages. For more information about IFRAME elements, visit this Microsoft Developer Network (MSDN) Web site.

How could an attacker exploit the vulnerability?
An attacker could exploit this vulnerability by creating a malicious Web page and persuading the user to visit the page. When the user has visited the page, the attacker could access information from other Web sites, access local files on the system, or cause malicious code to run as the locally logged on user.

What systems are primarily at risk from the vulnerability?
This vulnerability requires a user to view Web sites for malicious action to occur. Therefore, any systems where Internet Explorer is used frequently, such as users' 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.

It should be noted that FRAME and IFRAME elements are not rendered in the restricted zone, which is the zone where Outlook Express and Outlook by default open HTML email messages. Exploitation of this vulnerability through e-mail therefore requires user interaction in the form of a malicious link in the e-mail message. See the Workarounds Section in this bulletin for more information about this.

Are Windows 98, Windows 98 Second Edition or Windows Millennium Edition critically affected by this vulnerability?
Yes. Windows 98, Windows 98 Second Edition, and Windows Millennium Edition are critically affected by this vulnerability. A Critical security update for these platforms is available and is provided as part of this security bulletin and can be downloaded from the Windows Update Web site. For more information about severity ratings, visit this Microsoft Web site.

What does the update do?
The update removes the vulnerability by modifying the way that Internet Explorer validates the length of a message while processing HTML elements.

When this security bulletin was issued, had this vulnerability been publicly disclosed?
Yes. This vulnerability has been publicly disclosed. It has been assigned Common Vulnerability and Exposure number CAN-2004-1050.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited?
Yes. When the security bulletin was released, Microsoft had received information that this vulnerability was being exploited.

Verifying Update Installation

  • Microsoft Baseline Security Analyzer

    To verify that a security update is installed on an affected system, you may be able to use the Microsoft Baseline Security Analyzer (MBSA) tool. This tool allows administrators to scan local and remote systems for missing security updates and for common security misconfigurations. For more information about MBSA, visit the Microsoft Baseline Security Analyzer Web site.

  • 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 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 the update installation. 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.

  • Registry Key Verification

    You may also be able to verify the files that this security update has installed by confirming that an isInstalled DWORD value with a data value of 1 exists in the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{839117ee-2132-4bae-a56a-42b50204c9b9}

  • Program Version Verification

    Confirm that Q889293 is listed in the Update Versions field in the About Internet Explorer dialog box

Security Resources:

Software Update Services:

By using Microsoft Software Update Services (SUS), administrators can quickly and reliably deploy the latest critical updates and security updates to Windows 2000 and Windows Server 2003-based servers, and to desktop systems that are running Windows 2000 Professional or Windows XP Professional.

For more information about how to deploy this security update with Software Update Services, visit the Software Update Services Web site.

Systems Management Server:

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, see the SMS 2003 Security Patch Management Web site. SMS 2.0 users can also use Software Updates Service Feature Pack to help deploy security updates. For information about SMS, visit the SMS Web site.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, see the following Web site. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
