Description

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.

Affected configurations

• gnome gnome display manager (< 3.36.2) • gnome gnome display manager (>= 3.38.0 < 3.38.2)
