graphics adapter, etc.

Security Fix(es):

  * An out-of-bounds read/write access flaw was found in the way QEMU's VGA
emulation with VESA BIOS Extensions (VBE) support performed read/write
operations using I/O port methods. A privileged guest user could use this
flaw to execute arbitrary code on the host with the privileges of the
host's QEMU process. (CVE-2016-3710)

  * Quick Emulator(QEMU) built with the virtio framework is vulnerable to an
unbounded memory allocation issue. It was found that a malicious guest user
could submit more requests than the virtqueue size permits. Processing a
request allocates a VirtQueueElement results in unbounded memory allocation
on the host controlled by the guest. (CVE-2016-5403)
