Gnome Shell

A vulnerability was found in GNOME Shell. GNOME Shell's lock screen allows an unauthenticated local user to view windows of the locked desktop session by using keyboard shortcuts to unlock the restricted functionality of the screenshot tool.

A locking protection bypass flaw was found in some versions of gnome-shell as shipped within CentOS Stream 8, when the "Application menu" or "Window list" GNOME extensions are enabled. This flaw allows a physical attacker who has access to a locked system to kill existing applications and start new ones as the locked user, even if the session is still locked.

An issue was discovered in certain configurations of GNOME gnome-shell through 3.36.4. When logging out of an account, the password box from the login dialog reappears with the password still visible. If the user had decided to have the password shown in cleartext at login time, it is then visible for a brief moment upon a logout. (If the password were never shown in cleartext, only the password length is revealed.)

It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.

The automatic screen lock functionality in GNOME Shell (aka gnome-shell) before 3.10 does not prevent access to the "Enter a Command" dialog, which allows physically proximate attackers to execute arbitrary commands by leveraging an unattended workstation.
