  script_tag(name:"insight", value:"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 ... [Please see the references for more information on the vulnerabilities]");
