Summary

Microsoft has released a cumulative patch for Internet Explorer. This cumulative patch includes updates for the issues that are described in the following Microsoft Knowledge Base article:
813489  (http://support.microsoft.com/kb/813489/EN-US/ ) MS03-015: April, 2003, Cumulative Patch for Internet Explorer
This cumulative patch also addresses the following newly discovered vulnerabilities:
  • There is a buffer-overrun vulnerability in Urlmon.dll that occurs because Internet Explorer does not correctly determine an object type that is returned from a Web server. An attacker might be able to exploit this vulnerability to run arbitrary code on your computer. Simply visiting an attacker's Web site might permit the attacker to exploit the vulnerability without any other action on your part. An attacker can also create an HTML e-mail message that tries to exploit this vulnerability.
  • There is a flaw in Shdocvw.dll that does not implement an appropriate block on a file-download dialog box. An attacker might be able to exploit this vulnerability to run arbitrary code on your computer. Simply visiting an attacker's Web site might permit the attacker to exploit the vulnerability without any other action on your part. An attacker can also create an HTML e-mail message that tries to exploit this vulnerability.
To exploit these flaws, an attacker must host a malicious Web site that contains a Web page that is designed to exploit this specific vulnerability. The attacker then must persuade users to visit the site. To use the HTML e-mail message attack vector, the attacker must create a specially formed HTML e-mail message and send it to the recipients.

Notes
  • As with the previous Internet Explorer cumulative patch that was released with bulletin MS02-015 (813489), this cumulative patch also sets the "Kill" bit on the following ActiveX controls:

  • Because this patch sets the Kill bit on the Microsoft HTML Help control, you may experience broken links in Help if you have not installed the updated HTML Help control from Microsoft Knowledge Base article 811630.

  • As with the previous Internet Explorer cumulative patches that were released with bulletins MS03-004 (810847) and MS02-015 (813489), this cumulative patch causes the window.showHelp method to stop functioning 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 update.

Removal Information

To remove this update, use the Add or Remove Programs tool (or the Add/Remove Programs tool) in Control Panel. Click Internet Explorer Q818529, and then click Change/Remove (or click Add/Remove ).

On Windows Server 2003 and Windows XP 64-Bit Edition Version 2003, system administrators can use the Spunist.exe utility to remove this patch. The Spuninst.exe program file is located in the %Windir%\$NTUninstallKB818529$\Spuninst folder. This utility supports the following Setup switches:
  • /? Show the list of installation switches.
  • /u Use Unattended mode.
  • /f Force other programs to quit when the computer shuts down.
  • /z Do not restart when installation is complete.
  • /q Use Quiet mode (no user interaction).
On all other versions of Windows, system administrators can use the Ieuninst.exe utility to remove this update. The Ieuninst.exe program file is located in the %Windir% folder and supports the following command-line switches:
  • /? Show the list of supported switches.
  • /z Do not restart when installation is complete.
  • /q Use Quiet mode (no user interaction).
For example, to remove this update quietly, use the following command:
c:\windows\ieuninst /q c:\windows\inf\q818529.inf
Note This command line assumes that Windows is installed in the C:\Windows folder.

Known Issues

  • On a Windows 2000-based or on a Windows XP-based computer, you can install the 813489 critical update after you install the 818529 critical update. If you do this, the updated files in the 818529 critical update are replaced by the older files in the 813489 critical update. To resolve this issue, reinstall the 818529 critical update.
  • You can install the Internet Explorer 5.5 SP2 version of the 818529 critical update on a Windows 2000 SP3-based computer that is running Internet Explorer 5.01 SP3. To resolve this issue, remove the Internet Explorer 5.5 SP2 version of the 818529 critical update, and then install the Internet Explorer 5.01 SP3 version of the 818529 critical update. Administrators can use the Ieuninst.exe tool to remove the Internet Explorer 5.5 SP2 update as described in the "Removal Information" section of this article. For example, to remove the update quietly, use the following command:
    c:\windows\ieuninst /q c:\windows\inf\q818529.inf
    Note This command assumes that Windows is installed in the C:\Windows folder.
  • After you remove the 818529 critical update, you cannot remove previous cumulative updates for Internet Explorer (such as the 813489 critical update). This behavior is by design. Removing is supported only for the last cumulative update that you installed.
