  These security issues were fixed:

  - CVE-2013-4527: Buffer overflow in hw/timer/hpet.c might have allowed
  remote attackers to execute arbitrary code via vectors related to the
  number of timers (bsc#964746).

  - CVE-2013-4529: Buffer overflow in hw/pci/pcie_aer.c allowed remote
  attackers to cause a denial of service and possibly execute arbitrary
  code via a large log_num value in a savevm image (bsc#964929).

  - CVE-2013-4530: Buffer overflow in hw/ssi/pl022.c allowed remote
  attackers to cause a denial of service or possibly execute arbitrary
  code via crafted tx_fifo_head and rx_fifo_head values in a savevm image
  (bsc#964950).

  - CVE-2013-4533: Buffer overflow in the pxa2xx_ssp_load function in
  hw/arm/pxa2xx.c allowed remote attackers to cause a denial of service or
  possibly execute arbitrary code via a crafted s- rx_level value in a
  savevm image (bsc#964644).

  - 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 (bsc#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 (bsc#962642).

  - CVE-2013-4538: Multiple buffer overflows in the ssd0323_load function in
  hw/display/ssd0323.c allowed remote attackers to cause a denial of
  service (memory corruption) or possibly execute arbitrary code via
  crafted (1) cmd_len, (2) row, or (3) col values  (4) row_start and
  row_end values  or (5) col_star and col_end values in a savevm image
  (bsc#962335).

  - CVE-2013-4539: Multiple buffer overflows in the tsc210x_load function in
  hw/input/tsc210x.c might have allowed remote attackers to execute
  arbitrary code via a crafted (1) precision, (2) nextprecision, (3)
  function, or (4) nextfunction value in a savevm image (bsc#962758).

  - 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 (bsc#964925).

  - CVE-2014-3640: The sosendto function in slirp/udp.c allowed local users
  to cause a denial of service (NULL pointer dereference) by sending a udp
  packet with a value of 0 in the source port and address, which triggers
  access of an uninitialized socket (bsc#965112).

  - CVE-2014-3689: The vmware-vga driver (hw/display/vmware_vga.c) allowed
  local guest users to write to qemu memory locations  ...
