    gnupg: CVE-2018-9234
    
    * CVE-2018-9234
    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.
    
    Affects gnupg <= 2.2.5
