Telia: Misissued certificate - invalid dnsName

Telia Company issued a certificate with an invalid dnsName due to a trailing space, which was reported on January 25, 2019. The certificate was not revoked until January 31, 2019, after an internal investigation determined it did not pose an urgent security concern. Telia has since improved its procedures for handling such incidents, including updating its contact methods for urgent issues and conducting a mass scan that identified another similar misissued certificate. The incident report and subsequent actions have been documented and addressed.
