   An update that solves 19 vulnerabilities and has one errata
   is now available.

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.
