    (bsc#975700)

    - CVE-2014-9718: Fixed the handling of malformed or short ide PRDTs to
    avoid any opportunity for guest to cause DoS by abusing that interface
    (bsc#928393)
    - CVE-2014-3689: Fixed insufficient parameter validation in rectangle
    functions (bsc#901508)
    - CVE-2014-3615: The VGA emulator in QEMU allowed local guest users to
    read host memory by setting the display to a high resolution
    (bsc#895528).
    - CVE-2015-5239: Integer overflow in vnc_client_read() and
    protocol_client_msg() (bsc#944463).
    - 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

    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).
    - CVE-2015-7549: PCI null pointer dereferences (bsc#958917).

    (bsc#960334).

    (bsc#960725).
    - CVE-2016-1568: AHCI use-after-free in aio port commands (bsc#961332).
    - CVE-2016-1714: Potential OOB memory access in processing firmware
    configuration (bsc#961691).
    - CVE-2016-1922: NULL pointer dereference when processing hmp i/o command
    (bsc#962320).
    - CVE-2016-1981: Potential DoS (infinite loop) in e1000 device emulation
    by malicious privileged user within guest (bsc#963782).
    - CVE-2016-2198: Malicious privileged guest user were able to cause DoS by
