    Description:

    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)

    This non-security issue was fixed:
    - bsc#1000048: Fix migration failure where target host is a soon to be
    released SLES 12 SP2. Qemu's spice code gets an assertion.
