NVD Description

Note: Versions mentioned in the description apply only to the upstream gnome-shell-extension-launch-new-instance package and not the gnome-shell-extension-launch-new-instance package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
