MS03-040: October, 2003, Cumulative Patch for Internet Explorer


View products that this article applies to.

Symptoms

This is a cumulative security patch for Microsoft Internet Explorer that includes the functionality of all previously released patches for Internet Explorer 5.01, 5.5, and 6. Additionally, this security patch eliminates the following newly discovered vulnerabilities:
  • A vulnerability that occurs because Internet Explorer does not correctly determine an object type that is returned from a Web server in a pop-up window. An attacker who exploits this vulnerability could run arbitrary programs on your computer. If you were to visit an attacker's Web site, the attacker could exploit this vulnerability without any other action on your part. An attacker could also create an HTML�based e-mail message that could exploit this vulnerability.
  • A vulnerability that occurs because Internet Explorer does not correctly determine an object type that is returned from a Web server during XML data binding. An attacker who exploits this vulnerability could run arbitrary programs on your computer. If you were to visit an attacker's Web site, the attacker could exploit this vulnerability without any other action on your part. An attacker could also create an HTML�based e-mail message that could exploit this vulnerability.
Microsoft has changed the method that Internet Explorer uses to handle Dynamic HTML (DHTML) Behaviors in the Internet Explorer Restricted zone. An attacker who exploits a separate vulnerability could cause Internet Explorer to run script code in the security context of the Internet zone. Additionally, an attacker could use the Microsoft Windows Media Player ability to open Web addresses (or URLs) in the context of the Local Computer zone from a separate zone to construct an attack. An attacker could also create an HTML-based e-mail message that could exploit this behavior.

To exploit these flaws, the attacker would have to create a specially formed HTML�based e-mail message and send the message to you. Or, an attacker could host a malicious Web site that contains a Web page that is designed to exploit these vulnerabilities. The attacker would then have to persuade you to visit that Web site.

As with the previous Internet Explorer cumulative security patch that was released with security bulletin MS03-032 (822925), this cumulative patch causes the window.showHelp method to stop working if you have not applied the HTML Help update. If you have installed the updated HTML Help control from Microsoft Knowledge Base article 811630, you can still use HTML Help functionality after you apply this security patch. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
811630 HTML Help update to limit functionality when it is invoked with the window.showHelp( ) method
In addition to applying this security patch, Microsoft recommends that you also install the Windows Media Player update that is described in Microsoft Knowledge Base article 828026. For more information, click the following article number to view the article in the Microsoft Knowledge Base:
828026 Update for Windows Media Player URL script command behavior
This update is available from the Microsoft Windows Update Web site and from the Microsoft Download Center for all supported versions of Windows Media Player. Although it is not a security patch, this update contains a change to the behavior of the Windows Media Player ability to open Web addresses. This change can help to protect against DHTML behavior-based attacks. Specifically, this update restricts the Windows Media Player ability to open Web addresses in the Local Computer zone from other zones.

Mitigating Factors

  • By default, Internet Explorer on Windows Server 2003 runs in Enhanced Security Configuration. This default Internet Explorer configuration helps to block these attacks. If Internet Explorer Enhanced Security Configuration has been disabled, the protections that help to prevent these vulnerabilities from being exploited are removed.
  • In the Web-based attack scenario, the attacker would have to host a Web site that contains a Web page to exploit these vulnerabilities. An attacker would have no way to force you to visit a malicious Web site except for the HTML e-mail message vector. Instead, the attacker would have to lure you to the site, typically by causing you to click a link that takes you to the attacker's site.
  • Exploiting the vulnerability would allow the attacker only the same credentials as your credentials. Accounts that are configured to have few credentials on the computer are at less risk than accounts that operate with administrator credentials.
Notes
  • As with the previous Internet Explorer cumulative security patch that was released with security bulletin MS03-032 (822925), this cumulative security patch also sets the Kill bit on the following ActiveX controls:

    Microsoft HTML Help controlHhctrl.ocxADB880A6-D8FF-11CF-9377-00AA003B7A11323255

Workaround

These workarounds are temporary measures because they only help to block paths of attack. These workarounds do not correct the underlying vulnerability. Microsoft encourages you to install the security patch at your earliest opportunity.

The following workarounds are intended to give you information to help to protect your computer from attack.
  • Prompt before running ActiveX controls in the Internet and Intranet zones

    You can help to protect against this vulnerability by changing your settings for the Internet security zone to prompt you before running ActiveX components. To do this, follow these steps:
    1. In Internet Explorer, click Internet Options on the Tools menu.
    2. Click the Security tab.
    3. Click the Internet zone, and then click Custom Level.
    4. Under Run ActiveX controls and plug-ins, click Prompt .
    5. Click OK.
    6. Click the Local Intranet zone, and then click Custom Level.
    7. Under Run ActiveX controls and plug-ins, click Prompt.
    8. Click OK, and then click OK to return to Internet Explorer.
  • Restrict Web sites to only your trusted Web sites

    After you configure Internet Explorer to prompt you before running ActiveX controls in the Internet and the Local Intranet zone, you can add sites that you trust to a list of trusted sites. This allows you to continue using trusted Web sites exactly as you do today, while helping to protect you from the vulnerability that this article describes on untrusted sites. To do this, follow these steps:
    1. In Internet Explorer, click Internet Options on the Tools menu.
    2. Click the Security tab.
    3. Click the Trusted Sites zone, and then click Sites.
    4. If you want to add sites that do not require an encrypted channel, click to clear the Require server verification (https:) for all sites in this zone check box.
    5. In the Add this Web Site to the zone box, type the Web address (or URL) of a site that you trust, and then click Add. Repeat this for each site that you want to add to the Trusted Sites zone.
    6. Click OK and then click OK to accept the changes and return to Internet Explorer. Add any sites that you trust not to take malicious action on your computer. For example, you may want to add the "http://update.microsoft.com" site. This is the Microsoft site that hosts the security patch that this article describes; this site uses an ActiveX control to install the security patch.
  • If you are using Microsoft Outlook 2002 or Microsoft Outlook Express 6 SP1 or later, read-email messages in plain text to help to protect yourself from the HTML e-mail message attack vector

    If you use Outlook 2002 or Outlook Express 6 SP1 or later, you can turn on a feature to view all e-mail messages that are not digitally signed or encrypted in plain text only. Digitally signed or encrypted e-mail messages are not affected by this setting and you can view them in their original formats.

Known Issues

  • To correctly remove (uninstall) more than one cumulative update for Internet Explorer on a computer that is running Windows Server 2003 or that is running Windows XP 64-Bit Edition, Version 2003, you must remove the updates in the same order that they were installed. For example, if you install 818529, and you then install 828750, you must remove 828750 before you remove 818529.
  • On a computer that is running Windows XP, Windows 2000, Windows NT 4.0, Windows Millennium Edition, or Windows 98 Second Edition, after you remove the 828750 critical update, you cannot remove previous cumulative updates for Internet Explorer (such as the 818529 critical update). This behavior is by design. Removing is supported only for the last cumulative update that you installed.
