In March, 2001, VeriSign, Inc. announced that it had issued two digital certificates to an individual who fraudulently claimed to be a Microsoft employee. This issue is discussed at length in Microsoft Security Bulletin MS01-017
(http://www.microsoft.com/technet/security/bulletin/ms01-017.mspx). VeriSign has revoked these certificates, and they are listed in the current VeriSign Certificate Revocation List (CRL). However, because the VeriSign code-signing certificates do not specify a CRL Distribution Point (CDP), it is not possible for any browser's CRL-checking mechanism to locate and use the VeriSign CRL. Microsoft has developed an update that rectifies this problem. The update package includes a CRL that contains the two certificates, and an installable revocation handler that consults the CRL on the local computer, rather than attempting to use the CDP mechanism.
