Description Mike A. Harris 2004-03-12 09:55:24 UTC 
In the xorg source tree, and probably XFree86 too, the following
files contain calls to mprotect() in which the return code is
not checked, so if it fails for any reason, strange behaviour
may result:

xc/lib/Xxf86dga/XF86DGA.c
xc/lib/Xxf86dga/XF86DGA2.c
xc/programs/Xserver/hw/xfree86/loader/elfloader.c
xc/programs/Xserver/hw/xfree86/loader/loader.c
xc/programs/Xserver/hw/xfree86/os-support/linux/drm/kernel/drmstat.c

Just noticed these and don't have time to fix right now, so logging
here for future fixing.

This should be filed upstream I guess.  With a patch to fix it or
without, either way so that it is tracked somewhere.
