DESCRIPTION:
Microsoft has issued patches to fix a vulnerability in Microsoft
Windows (Internet Explorer) allowing malicious HTML documents like
web pages or emails to install arbitrary ActiveX controls.

The problem is that Microsoft Windows fails to present the user with
an approval dialog under certain low memory conditions. When this
occurs ActiveX controls will be installed silently. Malicious HTML
documents may be able to cause low memory conditions.

This vulnerability can't be exploited on Microsoft Windows 2003 if
Internet Explorer runs in Enhanced Security Configuration.

SOLUTION:
Microsoft has issued patches:

The patches are available from WindowsUpdate or from:
