"Pedro Ribeiro discovered that the X.Org X server incorrectly handled
memory operations when handling ImageText requests. An attacker could
use this issue to cause X.Org to crash, or to possibly execute
arbitrary code. (CVE-2013-4396)

It was discovered that non-root X.Org X servers such as Xephyr
incorrectly used cached xkb files. A local attacker could use this
flaw to cause a xkb cache file to be loaded by another user, resulting
in a denial of service. (CVE-2013-1056).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

applications when Xfixes extension is enabled in NX. Thanks to Ulrich
Sibiller! o Adapt X11 launchd socket path for recent Mac OS X
versions. o Fix Xinerama on Debian/Ubuntu installation (only worked on
systems that had dpkg-dev installed) and all RPM based distros. o
Partly make nxcomp aware of nx-libs's four-digit version string.
Thanks to Nito Martinez from TheQVD project!

  - Fix unowned directories

    - Minor cleanup
