NVD Description
Note: Versions mentioned in the description apply only to the upstream gnupg2 package and not the gnupg2 package as distributed by Ubuntu.
GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey.
