xorg-server: Security Advisory - xorg-server - CVE-2015-0255

Updated x11-server packages fix security vulnerability:

Olivier Fourdan from Red Hat has discovered a protocol handling issue in
the way the X server code base handles the XkbSetGeometry request, where
the server trusts the client to send valid string lengths. A malicious
client with string lengths exceeding the request length can cause the server
to copy adjacent memory data into the XKB structs. This data is then
available to the client via the XkbGetGeometry request. This can lead to
information disclosure issues, as well as possibly a denial of service if a
similar request can cause the server to crash (CVE-2015-0255).
