CVE-2020-16125  (opens in a new tab)
CWE-754  (opens in a new tab)

How to fix?

Upgrade Ubuntu:25.04 gdm3 to version 3.38.1-2ubuntu1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream gdm3 package and not the gdm3 package as distributed by Ubuntu. See How to fix? for Ubuntu:25.04 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.
