Gerv, Yes. We'll be revoking both of those. A date is yet to be determined.

RE: Certificates with reserved IP addresses
Hey Ryan, Here's the report from CTJ: Number of affected certificates: One. After receiving the revocation request from DigiCert, CTJ scanned their certificate database for additional certificates. This is the only active certificate with a reserved IP. CTJ issued the g2-sanfull01.ctjssl.info for its own use. Cause of missing the revocation: This certificate was identified as requiring revocation back in February 2016. When this issued, they had already blocked all renewals and issuance of certificates with internal names/IP addresses. Although the certificate was scheduled for revocation after CTJ moved away using the IP address, they forgot to revoke this last cert. Because it was one certificate, CTJ did not automate the revocation, making it subject to human error and forgetfulness. Remediation actions: CTJ is revoking this cert. CTJ is also implementing a CABLint-like process to check all certificates each time industry standards change. They are scanning crt.sh daily to verify the compliance of all new certs.

RE: Certificates with reserved IP addresses
Dear Ryan, Here is an initial, interim response to your email as it relates to certificates issued by the TI Trust Technologies Global CA. (Jeremy Rowley or I will be sending you a separate email shortly that reports on this issue with regard to Cybertrust Japan.) I will supplement this response as more information becomes available. Explanation to the community about how/why this happened: Apparently Telecom Italia Trust Technologies does not have adequate Baseline-Requirements filters in place to catch these. How many certificates it affected: Only the 5 listed at <https://misissued.com/batch/7/> https://misissued.com/batch/7/, as far as we know. What steps DigiCert is taking to prevent these issues in the future?: As a result of this and other recent issues, DigiCert is bringing certificate issuance for TI Trust Technologies in-house. We will be revoking CA certificate serial no. 07279ca7 issued to TI Trust Technologies Global CA. The key ceremony to create a new in-house CA is scheduled for Wednesday, 23 August, 2017. Do you have details about why DigiCert failed to detect these, and what steps DigiCert has in place to ensure compliance from its subordinate CAs? DigiCert uses some of the same tools used by others to monitor and detect mis-issuance by external, cross-certified CAs. These include crt.sh, cablint, and Censys.IO. As illustrated in this case, external CAs may be revoked if they do not comply. Whenever DigiCert is made aware of the non-compliance of an external CA, it contacts the operator of that CA and requests that non-compliant certificates be revoked, that the CA scan its records for other certificates with the same infirmity, and that it patch its systems so that the issue does not recur. On a proactive basis, DigiCert regularly advises external CAs of new requirements in the Baseline Requirements or browser root programs and asks these external CAs to ensure their ongoing compliance. Contracts with such entities also require compliance with the requirements.

Congratulations on finding something not caught by certlint. It turns out that cabtlint does zero checks for reserved IPs. Something else for my TODO list.
