  These security issues were fixed:

  - CVE-2016-2392: NULL pointer dereference in remote NDIS control message
  handling (bsc#967012).

  - CVE-2015-5239: Integer overflow in vnc_client_read() and
  protocol_client_msg() (bsc#944463).

  - CVE-2016-2270: Xen allowed local guest administrators to cause a denial
  of service (host reboot) via vectors related to multiple mappings of
  MMIO pages with different cachability settings  (boo#965315).

  - CVE-2016-2538: Integer overflow in remote NDIS control message handling
  (bsc#967969).

  - CVE-2015-7512: Buffer overflow in the pcnet_receive function in
  hw/net/pcnet.c, when a guest NIC has a larger MTU, allowed remote
  attackers to cause a denial of service (guest OS crash) or execute
  arbitrary code via a large packet (boo#962360).

  - CVE-2014-3689: The vmware-vga driver (hw/display/vmware_vga.c) allowed
  local guest users to write to qemu memory locations and gain privileges
  via unspecified parameters related to rectangle handling (boo#962611).

  - CVE-2015-5278: Infinite loop in ne2000_receive() function (bsc#945989).

  - CVE-2016-1568: AHCI use-after-free vulnerability in aio port commands
  (bsc#961332).

  - CVE-2016-1981: e1000 infinite loop in start_xmit and e1000_receive_iov
  routines (bsc#963782).

  - CVE-2016-2198: EHCI NULL pointer dereference in ehci_caps_write
  (bsc#964413).

  - CVE-2015-6815: e1000: infinite loop issue (bsc#944697).

  - CVE-2014-0222: Integer overflow in the qcow_open function in
  block/qcow.c allowed remote attackers to cause a denial of service
  (crash) via a large L2 table in a QCOW version 1 image (boo#964925).

  - CVE-2015-6855: hw/ide/core.c did not properly restrict the commands
  accepted by an ATAPI device, which allowed guest users to cause a denial
  of service or possibly have unspecified other impact via certain IDE
  commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty
  drive, which triggers a divide-by-zero error and instance crash
  (boo#965156).

  - CVE-2016-2271: VMX in using an Intel or Cyrix CPU, allowed local HVM
  guest users to cause a denial of service (guest crash) via vectors
  related to a non-canonical RIP (boo#965317).

  - CVE-2013-4534: Buffer overflow in hw/intc/openpic.c allowed remote
  attackers to cause a denial of service or possibly execute arbitrary
  code via vectors related to IRQDest elements (boo#964452).

  - CVE-2013-4537: The ssi_sd_transfer function in hw/sd/ssi-sd.c allowed
  remote attackers to execute arbitrary code via a crafted arglen value in
  a savevm image (boo#962642).
