Security Fix(es):

  * An out of bounds array access issue was found in the Xen virtual machine
monitor, built with the QEMU ioport support. It could occur while doing
ioport read/write operations, if guest was to supply a 32bit address
parameter. A privileged guest user/process could use this flaw to
potentially escalate their privileges on a host. (CVE-2016-9637)

Red Hat would like to thank the Xen project for reporting this issue.");
