AI Summary

This case involves Camerfirma, which discovered that some of its certificates were issued with duplicate Subject Alternative Names (SANs) and without the required localityName or stateOrProvinceName. The issue was identified during an internal review and subsequently reported to Mozilla. Camerfirma communicated the problem to affected customers, initiated revocation of the incorrectly issued certificates, and began reissuing compliant certificates. By April 24, 2017, all affected certificates had been re-issued, and the majority of the problematic certificates were revoked. The case has been resolved with all actions completed.
