gfxmenu/gui: Check printf() format in the gui_progress_bar and gui_label
...
The gui_progress_bar and gui_label components can display the timeout
value. The format string can be set through a theme file. This patch
adds a validation step to the format string.
If a user loads a theme file into the GRUB without this patch then
a GUI label with the following settings
+ label {
...
id = "__timeout__"
text = "%s"
}
will interpret the current timeout value as string pointer and print the
memory at that position on the screen. It is not desired behavior.
