    Kevin Backhouse discovered that GDM incorrectly launched the initial setup tool when the accountsservice daemon was not reachable. A local attacker able to cause accountsservice to crash or stop responding could trick GDM into launching the initial setup tool and create a privileged user (CVE-2020-16125).
