The following security issues have been fixed:

 * CVE-2013-6424: Integer underflow in the xTrapezoidValid macro in
 render/picture.h in X.Org allowed context-dependent attackers to
 cause a denial of service (crash) via a negative bottom value.
 * CVE-2013-4396: Use-after-free vulnerability in the doImageText
 function in dix/dixfonts.c in the xorg-server module before 1.14.4
 in X.Org X11 allowed remote authenticated users to cause a denial of
 service (daemon crash) or possibly execute arbitrary code via a
 crafted ImageText request that triggers memory-allocation failure.
 * CVE-2013-1940: X.Org X server did not properly restrict access to
 input events when adding a new hot-plug device, which might have
 allowed physically proximate attackers to obtain sensitive
 information, as demonstrated by reading passwords from a tty.

The following non-security issues have been fixed:

 * rfbAuthReenable is accessing rfbClient structure that was in most
 cases already freed. It actually needs only ScreenPtr, so pass it
 directly. (bnc#816813)
 * Memory leaks in ARGB cursor handling. (bnc#813178, bnc#813683)

Security Issues:

 * CVE-2013-1940
 * CVE-2013-4396
