Posted on 28 August 2013
Revision Note: V1.1 (August 27, 2013): Revised advisory to announce that the 2862973 update is available from the Microsoft Update Catalog.
Summary: Microsoft is announcing the availability of an update for supported editions of Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012 that restricts the use of certificates with MD5 hashes.
