CVE-2019-3820

An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.

MEDIUM 4.3EPSS 0.50%

Does this matter?

Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.

Description

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.
