Microsoft releases Security Advisory 2641690, updates Untrusted Certificate Store

Thursday, November 10, 2011

Hi everyone, As a follow-up to Friday’s blog post, today we released Security Advisory 2641690 to notify customers that we revoked the trust of DigiCert Sdn.Bhd in an update that moves two Intermediate Certificate Authorities (CA) certificates to the Microsoft Untrusted Certificate Store. We made this decision after Entrust, Inc., a CA in the Microsoft Root Certificate Program, notified us that one of its subordinate CAs issued 22 certificates with weak 512 bit keys, a violation of Microsoft’s Root Certificate Program requirements.
