  functions (bsc#901508)

  read host memory by setting the display to a high resolution
  (bsc#895528).
• CVE-2015-5239: Integer overflow in vnc_client_read() and

• CVE-2015-5278: Infinite loop in ne2000_receive() function (bsc#945989).
• CVE-2015-5279: Heap-based buffer overflow in the ne2000_receive function
  in hw/net/ne2000.c in QEMU allowed guest OS users to cause a denial of
  service (instance crash) or possibly execute arbitrary code via vectors
  related to receiving packets (bsc#945987).
• CVE-2015-5745: Buffer overflow in virtio-serial (bsc#940929).
• CVE-2015-6855: hw/ide/core.c in QEMU 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 (bsc#945404).
• CVE-2015-7295: hw/virtio/virtio.c in the Virtual Network Device
  (virtio-net) support in QEMU, when big or mergeable receive buffers are
  not supported, allowed remote attackers to cause a denial of service
  (guest network consumption) via a flood of jumbo frames on the (1)
  tuntap or (2) macvtap interface (bsc#947159).

  (bsc#961358).
• CVE-2015-8619: Potential DoS for long HMP sendkey command argument
  (bsc#960334).

  by malicious privileged user within guest (bsc#963782).
