DigiCert: Failure to properly encode Subject name

DigiCert identified a failure to properly encode subject names in certain certificates, leading to non-compliance with the Baseline Requirements. Following an internal audit, DigiCert revoked 33 affected certificates and reported the incident to Mozilla. The issue stemmed from a previous compliance patch that did not retroactively address existing certificates. DigiCert has since implemented comprehensive scanning and compliance measures to prevent future occurrences.
