"qemu was updated to fix 19 security issues. These security issues were
fixed :

  - CVE-2016-2392: The is_rndis function in the USB Net
    device emulator (hw/usb/dev-network.c) in QEMU did not
    properly validate USB configuration descriptor objects,
    which allowed local guest OS administrators to cause a
    denial of service (NULL pointer dereference and QEMU
    process crash) via vectors involving a remote NDIS
    control message packet (bsc#967012)

  - CVE-2016-2391: The ohci_bus_start function in the USB
    OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU
    allowed local guest OS administrators to cause a denial
    of service (NULL pointer dereference and QEMU process
    crash) via vectors related to multiple eof_timers
    (bsc#967013)

  - CVE-2016-5106: The megasas_dcmd_set_properties function
    in hw/scsi/megasas.c in QEMU, when built with MegaRAID
    SAS 8708EM2 Host Bus Adapter emulation support, allowed
    local guest administrators to cause a denial of service
    (out-of-bounds write access) via vectors involving a
    MegaRAID Firmware Interface (MFI) command (bsc#982018)

  - CVE-2016-5105: The megasas_dcmd_cfg_read function in
    hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS
    8708EM2 Host Bus Adapter emulation support, used an
    uninitialized variable, which allowed local guest
    administrators to read host memory via vectors involving
    a MegaRAID Firmware Interface (MFI) command (bsc#982017)

  - CVE-2016-5107: The megasas_lookup_frame function in
    QEMU, when built with MegaRAID SAS 8708EM2 Host Bus
    Adapter emulation support, allowed local guest OS
    administrators to cause a denial of service
    (out-of-bounds read and crash) via unspecified vectors
    (bsc#982019)

  - CVE-2016-5126: Heap-based buffer overflow in the
    iscsi_aio_ioctl function in block/iscsi.c in QEMU
    allowed local guest OS users to cause a denial of
    service (QEMU process crash) or possibly execute
    arbitrary code via a crafted iSCSI asynchronous I/O
    ioctl call (bsc#982285)

  - CVE-2016-4454: The vmsvga_fifo_read_raw function in
    hw/display/vmware_vga.c in QEMU allowed local guest OS
    administrators to obtain sensitive host memory
    information or cause a denial of service (QEMU process
    crash) by changing FIFO registers and issuing a VGA
    command, which triggers an out-of-bounds read
    (bsc#982222)

  - CVE-2016-4453: The vmsvga_fifo_run function in
    hw/display/vmware_vga.c in QEMU allowed local guest OS
    administrators to cause a denial of service (infinite
    loop and QEMU process crash) via a VGA command
    (bsc#982223)

  - CVE-2016-5338: The (1) esp_reg_read and (2)
    esp_reg_write functions in hw/scsi/esp.c in QEMU allowed
    local guest OS administrators to cause a denial of
    service (QEMU process crash) or execute arbitrary code
    on the QEMU host via vectors related to the information
    transfer buffer (bsc#983982)

  - CVE-2016-5337: The megasas_ctrl_get_info function in
    hw/scsi/megasas.c in QEMU allowed local guest OS
    administrators to obtain sensitive host memory
    information via vectors related to reading device
    control information (bsc#983961)

  - CVE-2016-5238: The get_cmd function in hw/scsi/esp.c in
    QEMU allowed local guest OS administrators to cause a
    denial of service (out-of-bounds write and QEMU process
    crash) via vectors related to reading from the
    information transfer buffer in non-DMA mode (bsc#982959)

  - CVE-2016-5403: The virtqueue_pop function in
    hw/virtio/virtio.c in QEMU allowed local guest OS
    administrators to cause a denial of service (memory
    consumption and QEMU process crash) by submitting
    requests without waiting for completion (bsc#991080)

  - CVE-2016-6490: Infinite loop in the virtio framework. A
    privileged user inside the guest could have used this
    flaw to crash the Qemu instance on the host resulting in
    DoS (bsc#991466)

  - CVE-2016-6888: Integer overflow in packet initialisation
    in VMXNET3 device driver. A privileged user inside guest
    could have used this flaw to crash the Qemu instance
    resulting in DoS (bsc#994771)

  - CVE-2016-6833: Use-after-free issue in the VMWARE
    VMXNET3 NIC device support. A privileged user inside
    guest could have used this issue to crash the Qemu
    instance resulting in DoS (bsc#994774)

  - CVE-2016-7116: Host directory sharing via Plan 9 File
    System(9pfs) was vulnerable to a directory/path
    traversal issue. A privileged user inside guest could
    have used this flaw to access undue files on the host
    (bsc#996441)

  - CVE-2016-6836: VMWARE VMXNET3 NIC device support was
    leaging information leakage. A privileged user inside
    guest could have used this to leak host memory bytes to
    a guest (bsc#994760)

  - CVE-2016-7155: In the VMWARE PVSCSI paravirtual SCSI bus
    a OOB access and/or infinite loop issue could have
    allowed a privileged user inside guest to crash the Qemu
    process resulting in DoS (bsc#997858)

  - CVE-2016-7156: In the VMWARE PVSCSI paravirtual SCSI bus
    a infinite loop issue could have allowed a privileged
    user inside guest to crash the Qemu process resulting in
    DoS (bsc#997859)

The update package also includes non-security fixes. See advisory for
