   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:


   The X Server was updated to fix 1 security issues and 4 bugs:

   Security issues:
   - CVE-2015-3418: Fixed a regression introduced by CVE-2014-8092 in
     PutImage that caused crashes when called with 0 height (bnc#928520).

   Bugs fixed:
   - Xephyr: Don't crash when no command line argument is specified The DDX
     specific command line parsing function only gets called if command line
     arguments are present. Therefore this function is not suitable to
     initialize mandatory global variables.  Replace main() instead.
     (bnc#925022)
   - Xephyr: Print default server display number if none is specified
     (bnc#925022)
   - Xephyr: Fix broken image when endianess of client machine and
     host-Xserver differ The image is created in the native byte order of the
     machine Xephyr is rendered on however drawn in the image byte order of
     the Xephyr server. Correct byte order in the xcb_image_t structure and
     convert to native before updating the window. If depths of Xephyr and
     host server differ this is already taken care of by the depth conversion
     routine. (bnc#923229).
   - Xephyr: Fix compile when debugging is enabled (bnc#925021)
   - Xephyr: Fix screen image draw for the non-Glamor & non-XHSM case
     xcb_image_put() prints the entire image, therefore don't use an offset.
     (bnc#925019)
