NVD Description
Note: Versions mentioned in the description apply only to the upstream glib2-devel package and not the glib2-devel package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
gdm3 versions before 3.36.2 or 3.38.2 would start gnome-initial-setup if gdm3 can't contact the accountservice service via dbus in a timely manner; on Ubuntu (and potentially derivatives) this could be be chained with an additional issue that could allow a local user to create a new privileged account.
