DigiCert preliminary incident report: CRLNumber sequence not strictly increasing within one CRL scope
DigiCert opened this bug as a preliminary incident report after a third party reported an issue with two DigiCert Issuing CA CRLs disclosed in CCADB. The report says the CRLs have the same scope and issuer and share one cRLNumber sequence. It also says that, in several observed instances, the cRLNumber decreased between versions, which the report notes is inconsistent with BR Section 7.2.2 and RFC 5280 Section 5.2.3. The thread provided here does not include any remediation, resolution, or follow-up beyond the initial disclosure. The case is therefore a self-disclosed compliance incident about CRLNumber sequencing.
- A third party reported that two CRLs for the same DigiCert Issuing CA scope and issuer shared one cRLNumber sequence and showed decreases between versions.
- DigiCert — DigiCert filed a preliminary incident report describing the CRLNumber sequencing issue and citing BR Section 7.2.2 and RFC 5280 Section 5.2.3.
