Vulnerability Assessment Summary
Checks for ms04-023 over the registry

Detailed Explanation for this Vulnerability Assessment

Summary :

Arbitrary code can be executed on the remote host through the web client.

Description :

The remote host is subject to two vulnerabilities in the HTML Help and showHelp
modules, which could permit a possible hacker to execute arbitrary code on the remote
host.

To exploit this flaw, a possible hacker would need to set up a rogue website
containing a malicious showHelp URL, and would need to lure a user on the
remote host to visit it. Once the user visits the web site, a buffer overflow
would permit the attacker to execute arbitrary commands with the rights
of the victim user.

Solution :

Microsoft has released a set of patches for Windows 2000, XP and 2003 :
