Hi,

The following vulnerability was published for gnupg2:

CVE-2018-9234[0]:
| 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

| signing subkey.

If you fix the vulnerability please also make sure to include the
