Description Huzaifa S. Sidhpurwala 2015-01-12 00:17:17 EST

Brian Smith reported that delegated Online Certificate Status Protocol (OCSP) responder certificates fail to recognize the id-pkix-ocsp-nocheck extension. If this extension is present in a delegated OCSP response signing certificate, it will be discarded if it is signed by such a certificate. This could result in a user connecting to a site with a revoked certificate.
