CVE-2020-27837 1 Gnome 1 Gnome Display Manager 2020-12-30 4.4 MEDIUM 6.4 MEDIUM
A flaw was found in GDM in versions prior to 3.38.2.1. A race condition in the handling of session shutdown makes it possible to bypass the lock screen for a user that has autologin enabled, accessing their session without authentication. This is similar to CVE-2017-12164, but requires more difficult conditions to exploit.
CVE-2020-16125 1 Gnome 1 Gnome Display Manager 2020-11-24 4.6 MEDIUM 6.8 MEDIUM
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.
CVE-2019-3825 3 Canonical, Gnome, Redhat 3 Ubuntu Linux, Gnome Display Manager, Enterprise Linux 2019-10-09 6.9 MEDIUM 6.4 MEDIUM
A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.
CVE-2017-12164 1 Gnome 1 Gnome Display Manager 2019-10-09 6.9 MEDIUM 6.4 MEDIUM
A flaw was discovered in gdm 3.24.1 where gdm greeter was no longer setting the ran_once boolean during autologin. If autologin was enabled for a victim, an attacker could simply select 'login as another user' to unlock their screen.
