   An update that solves 13 vulnerabilities and has two fixes
   is now available.

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)
