Update B again
Symantec issued a cert to one of its customers that did not comply with at least one provision of both the CA/Browser Forum Baseline Requirements and Mozilla policy. It was a 1024-bit cert which expired after the end of 2013. Symantec believed this was the only technical way to ensure continuity of service for the customer concerned.
This cert was issued directly from the root. Recently, Symantec have produced a 's [https://groups.google.com/forum/#!topic/mozilla.dev.security.policy/x_vrJtv7A0Y longer write-up] of the incident. In it, they point points out that issuance from the root is permitted by [https://cabforum.org/wp-content/uploads/Baseline_Requirements_V1_1_6.pdf version BRs 1.1.6], the version in force at the time, if 5 conditions are met, and they say they were met.
This cert was backdated, but that is not a BR or Mozilla policy violation, as long as it was not done to evade a technical control. It als so has  The cert had a short serial number. Entropy in the serial number is a SHOULD in BRs 1.1.6. 20 bits of entropy is a MUST in the Mozilla policy ([https://github.com/mozilla/pkipolicy/blob/2.2/rootstore/policy.md version 2.2]), but it doesn't say it has to be in the serial number - it could be that they randomised the notBefore time. I am told Microsoft removed the allowance for doing entropy in the Date field on 11th November 2013, so this was a violation of their policies. Symantec say that they got a verbal exception from Microsoft.
Symantec did not request permission to issue in advance, they disclosed the issuance at least a month after it had happened, and the replacement certificate (unlike the original) asserted a "BR Compliant" OID.
===Symantec Response===
Symantec self-reported this issuance to Mozilla [https://bugzilla.mozilla.org/show_bug.cgi?id=966350 via Bugzilla] at the end of January 2014. Even though a [https://bugzilla.mozilla.org/show_bug.cgi?id=966350#c2 question was asked] about the BR Compliance OID that the new cert asserted, they did not comment on the bug beyond the initial report. Recently, Symantec have produced a [https://groups.google.com/forum/#!topic/mozilla.dev.security.policy/x_vrJtv7A0Y longer write-up] of the incident.
