   An update that fixes 16 vulnerabilities is now available.

Description:

   kvm was updated to fix 16 security issues.

   These security issues were fixed:
   - CVE-2015-6815: e1000 NIC emulation support was vulnerable to an infinite
     loop issue. A privileged user inside guest could have used this flaw to
     crash the Qemu instance resulting in DoS.  (bsc#944697).
   - 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-2016-2392: 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-2016-4453: 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-2016-4454: 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-2016-5105: 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-2016-5106: 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-2016-5107: 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-2016-5238: 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-2016-5337: 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-2016-5338: 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-2016-5403: 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-2016-7116: 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-2014-7815: The set_pixel_format function in ui/vnc.c in QEMU allowed
     remote attackers to cause a denial of service (crash) via a small
     bytes_per_pixel value (bsc#902737).
