Updated x11-server packages fix security vulnerabilities

Ilja van Sprundel of IOActive discovered several security issues in the X.org X server, which may lead to privilege escalation or denial of service (CVE-2014-8091, CVE-2014-8092, CVE-2014-8093, CVE-2014-8094, CVE-2014-8095, CVE-2014-8096, CVE-2014-8097, CVE-2014-8098, CVE-2014-8099, CVE-2014-8100, CVE-2014-8101, CVE-2014-8102).

Recommended update for xorg-x11-server

This collective update for xorg-x11-server provides the following fixes:

* Fix a segmentation fault that can occur when X11 packets are
  forwarded between a client and a server with different endianess.
  (bnc#874903)
* Free software cursor backing pixmap when transition between screens.
  This fixes a crash in multi screen support when an assert gets hit.
  (bnc#880835)
* Ignore numlock in Xvnc. Following keys from VNC client will be
  already modulated by numlock on client side. (bnc#878446)
* Fix crash when Xinerama gets disabled after RanR12 is initialized.
  (bnc#878433)
* Prevent crash at the end of 2nd server generation when number of
  privates differ between 1st and 2nd. (bnc#883598)
* Move Xinerama disable when only one screen is present to main loop.
  (bnc#883598)
* Improve Xinerama command line option handling. (bnc#883598)
* Work around a possible crash when object belongs to a client that no
  longer exists. (bnc#883516)
* Try to make keyboard bell ring on all devices attached to master
  keyboard. (bnc#879019)
* Implement DeleteInputDeviceRequest in Xvnc to avoid server crash when
  the Xserver restarts after a server reset. (bnc#880745).
