Red Hat Security Advisory 2015-0535-01 - GNOME Shell and the packages it depends upon provide the core user interface of the Red Hat Enterprise Linux desktop, including functions such as navigating between windows and launching applications. It was found that the GNOME shell did not disable the Print Screen key when the screen was locked. This could allow an attacker with physical access to a system with a locked screen to crash the screen-locking application by creating a large amount of screenshots.
