"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).

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