    Description:


    qemu was updated to fix several issues.

    These security issues were fixed:

    - CVE-2016-9102: Memory leak in the v9fs_xattrcreate function in
    hw/9pfs/9p.c in allowed local guest OS administrators to cause a denial
    of service (memory consumption and QEMU process crash) via a large
    number of Txattrcreate messages with the same fid number (bsc#1014256).
    - CVE-2016-9103: The v9fs_xattrcreate function in hw/9pfs/9p.c in allowed
    local guest OS administrators to obtain sensitive host heap memory
    information by reading xattribute values writing to them (bsc#1007454).
    - CVE-2016-9381: Improper processing of shared rings allowing guest
    administrators take over the qemu process, elevating their privilege to
    that of the qemu process (bsc#1009109)
    - CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support
    was vulnerable to an infinite loop issue while receiving packets in
    'mcf_fec_receive'. A privileged user/process inside guest could have
    used this issue to crash the Qemu process on the host leading to DoS
    (bsc#1013285).
    - CVE-2016-9845: The Virtio GPU Device emulator support as vulnerable to
    an information leakage issue while processing the
    'VIRTIO_GPU_CMD_GET_CAPSET_INFO' command. A guest user/process could
    have used this flaw to leak contents of the host memory (bsc#1013767).
    - CVE-2016-9846: The Virtio GPU Device emulator support was vulnerable to
    a memory leakage issue while updating the cursor data in
    update_cursor_data_virgl. A guest user/process could have used this flaw
    to leak host memory bytes, resulting in DoS for the host (bsc#1013764).
    - CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a
    memory leakage flaw when destroying the USB redirector in
    'usbredir_handle_destroy'. A guest user/process could have used this
    issue to leak host memory, resulting in DoS for a host (bsc#1014109).
    - CVE-2016-9908: The Virtio GPU Device emulator support was vulnerable to
    an information leakage issue while processing the
    'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could have
    used this flaw to leak contents of the host memory (bsc#1014514).
    - CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory
    leakage issue while processing packet data in 'ehci_init_transfer'. A
    guest user/process could have used this issue to leak host memory,
    resulting in DoS for the host (bsc#1014111).
    - CVE-2016-9912: The Virtio GPU Device emulator support was vulnerable to
    a memory leakage issue while destroying gpu resource object in
    'virtio_gpu_resource_destroy'. A guest user/process could have used this
    flaw to leak host memory bytes, resulting in DoS for the host
    (bsc#1014112).
    - CVE-2016-9913: VirtFS was vulnerable to memory leakage issue via its
    '9p-handle' or '9p-proxy' backend drivers. A privileged user inside
    guest could have used this flaw to leak host memory, thus affecting
    other services on the host and/or potentially crash the Qemu process on
    the host (bsc#1014110).

    These non-security issues were fixed:

    - Fixed uint64 property parsing and add regression tests (bsc#937125)
    - Added a man page for kvm_stat
    - Fix crash in vte (bsc#1008519)
    - Various upstream commits targeted towards stable releases (bsc#1013341)
