  These security issues were fixed:

  - CVE-2017-15268: Qemu allowed remote attackers to cause a memory leak by
  triggering slow data-channel read operations, related to
  io/channel-websock.c (bsc#1062942).

  - CVE-2017-9524: The qemu-nbd server when built with the Network Block
  Device (NBD) Server support allowed remote attackers to cause a denial
  of service (segmentation fault and server crash) by leveraging failure
  to ensure that all initialization occurs talking to a client in the
  nbd_negotiate function (bsc#1043808).

  - CVE-2017-15289: The mode4and5 write functions allowed local OS guest
  privileged users to cause a denial of service (out-of-bounds write
  access and Qemu process crash) via vectors related to dst calculation
  (bsc#1063122)

  - CVE-2017-15038: Race condition in the v9fs_xattrwalk function local
  guest OS users to obtain sensitive information from host heap memory via
  vectors related to reading extended attributes (bsc#1062069)

  - CVE-2017-10911: The make_response function in the Linux kernel allowed
  guest OS users to obtain sensitive information from host OS (or other
  guest OS) kernel memory by leveraging the copying of uninitialized
  padding fields in Xen block-interface response structures (bsc#1057378)

  - CVE-2017-12809: The IDE disk and CD/DVD-ROM Emulator support allowed
  local guest OS privileged users to cause a denial of service (NULL
  pointer dereference and QEMU process crash) by flushing an empty CDROM
  device drive (bsc#1054724)

  - CVE-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote
  attackers to cause a denial of service (daemon crash) by disconnecting
  during a server-to-client reply attempt (bsc#1046636)

  - CVE-2017-10806: Stack-based buffer overflow allowed local guest OS users
  to cause a denial of service (QEMU process crash) via vectors related to
  logging debug messages (bsc#1047674)

  - CVE-2017-14167: Integer overflow in the load_multiboot function allowed
  local guest OS users to execute arbitrary code on the host via crafted
  multiboot header address values, which trigger an out-of-bounds write
  (bsc#1057585)

  - CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local
  guest OS users to cause a denial of service (out-of-bounds read) via a
  crafted DHCP options string (bsc#1049381)

  - CVE-2017-11334: The address_space_write_continue function allowed local
  guest OS privileged users to cause a denial of service (out-of-bounds
  access and guest instance crash) by leveraging use of qemu_map_ram_ptr
  to access guest ram block are ...
