Ricardo Salveti <ricardo.salveti@linaro.org> found one place where the randr code could use the randr screen private data without checking for null first. This happens when the X server is running with multiple screens, some of which are randr enabled and some of which are not. Applications making protocol requests to the non-randr screens can cause segfaults where the server touches the unset private structure. I audited the code and found two more possible problem spots; the trick to auditing for this issue was to look for functions not taking a RandR data structure and where there was no null screen private check above them in the call graph.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
