Firmaprofesional: AC Firmaprofesional - INFRAESTRUCTURA insufficient serial number entropy

Firmaprofesional identified an issue with SSL certificates issued by their AC Firmaprofesional - INFRAESTRUCTURA, which had insufficient serial number entropy of 63 bits instead of the required 64 bits. The problem was first noted on March 15, 2019, leading to an immediate halt in certificate issuance and the initiation of corrective measures. By July 31, 2019, all affected certificates had been revoked or expired, except for two critical certificates that were later revoked in August 2019. The CA has since updated its systems to ensure compliance with entropy requirements.
