What is CVE-2018-9234?

The GnuPG software versions 2.2.4 and 2.2.5 have a critical flaw where the configuration settings do not enforce the requirement that key certification must utilize an offline master Certify key. This leads to situations where key certifications can be issued that appear valid but are made using only a signing subkey, creating potential for misuse and unauthorized access.
