Microsoft Security Advisory (2718704)
Unauthorized Digital Certificates Could Allow Spoofing

Published: Sunday, June 03, 2012

Version: 1.0


General Information

Executive Summary

Microsoft is aware of active attacks using unauthorized digital certificates 
derived from a Microsoft Certificate Authority. An unauthorized certificate 
could be used to spoof content, perform phishing attacks, or perform 
man-in-the-middle attacks. This issue affects all supported releases of 
Microsoft Windows.

Microsoft is providing an update for all supported releases of Microsoft 
Windows. The update revokes the trust of the following intermediate CA 
certificates:

    Microsoft Enforced Licensing Intermediate PCA (2 certificates)
    Microsoft Enforced Licensing Registration Authority CA (SHA1)

Recommendation. For supported releases of Microsoft Windows, Microsoft 
recommends that customers apply the update immediately using update management 
software, or by checking for updates using the Microsoft Update service. For 
more information, see the Suggested Actions section of this advisory. For 
affected devices, no update is available at this time.
