CVE-2017-10971

			A user authenticated to an X Session could crash or execute code in the
context of the X Server by exploiting a stack overflow in the endianness
conversion of X Events.

CVE-2017-10972

			Uninitialized data in endianness conversion in the XEvent handling of the
			X.Org X Server allowed authenticated malicious users to access potentially
privileged data from the X server.

We recommend that you upgrade your xorg-server packages.
