Article contents

Summary

This article describes the following about this hotfix release:
  • The issues that are fixed by this hotfix package.
  • The prerequisites for installing the hotfix package.
  • Whether you must restart your computer after you install the hotfix package.
  • Whether the hotfix package is replaced by any other hotfix package.
  • Whether you must make any registry changes.
  • The files that are contained in the hotfix package.

Symptoms

After you apply the fixes that are in Microsoft Security Bulletin MS04-004 and Microsoft Knowledge Base article 832414, the Microsoft XML Parser (MSXML) user credentials may be cached. Then, MSXML may use user sessions incorrectly within a single Microsoft Internet Explorer process. For example, a user may successfully connect with the following function call:
xmlhttp.open("GET", "http://www.myserver.com/myfiles", false, "correctusername", "correctpassword")   
Then, the user may notice that the following call also succeeds when it is used subsequently in the same process:
xmlhttp.open("GET", "http://www.www.myserver.com.com/myfiles", false, "incorrectusername", "incorrectpassword") 
The second call should fail because the credentials are incorrect. However, the call succeeds because of changes in the default behavior of Internet Explorer after you apply the MS04-004 security update.

Cause

This behavior occurs because XMLHTTP incorrectly leaks connection credentials across user sessions.

Resolution

Hotfix information

To resolve this behavior, update your version of MSXML. To do this, visit one of the following Microsoft Web sites.

Note If you have MSXML 3.0 installed, you must install a service pack.
