Vulnerability in Microsoft XML Core Services Could Allow Remote Code Execution (928088)
A vulnerability exists in the XMLHTTP ActiveX control within Microsoft XML Core Services that could allow for remote code execution. An attacker could exploit the vulnerability by constructing a specially crafted Web page that could potentially allow remote code execution if a user visited that page or clicked a link in an e-mail message. An attacker who successfully exploited this vulnerability could take complete control of an affected system. However, user interaction is required to exploit this vulnerability.As far as I see this, once the page is visited the malware file will be downloaded and run because of the vulnerability in the XMLHTTP ActiveX control.
Make sure that this update is installed already by going to Add/Remove Programs in the Control Panel. It will not be listed under WIndows XP - Software Updates, but rather, will be listed as
MSXML 4 SP2 (KB927978)
If, for some reason, the update is not installed, please go the Security Bulletin page and click the Download the update link under Affected components for the version of MSXML that is currently installed.
In order to determine which version is installed if there are no MSXML packages listed in Add/Remove Programs,
check the WINDOWS\system32 folder for :
Msxml4.dll
and
Msxml6.dll
If either are present, right click it, choose Properties, and then click the Version tab.
The files contained in the update are the following Versions:
Msxml4.dll Version number 4.20.9841.0
Msxml6.dll Version number 6.0.3890.0
Both are dated 11/4/2006
If you've had an issue installing KB929798, then check to see if KB925672 is installed in Add/Remove Programs.
If it is, uninstall it, reboot, and then install KB929798, then reboot, as it supercedes it.
