  These security issues were fixed:

  - CVE-2017-7228: Broken check in memory_exchange() permitted PV guest
  breakout (bsc#1030442).

  - XSA-206: Unprivileged guests issuing writes to xenstore were able to
  stall progress of the control domain or driver domain, possibly leading
  to a Denial of Service (DoS) of the entire host (bsc#1030144).

  - CVE-2017-6505: The ohci_service_ed_list function in hw/usb/hcd-ohci.c
  allowed local guest OS users to cause a denial of service (infinite
  loop) via vectors involving the number of link endpoint list descriptors
  (bsc#1028235).

  These non-security issues were fixed:

  - bsc#1015348: libvirtd didn't not start during boot

  - bsc#1014136: kdump couldn't dump a kernel on SLES12-SP2 with Xen
  hypervisor.

  - bsc#1026236: Fixed paravirtualized performance

  - bsc#1022555: Timeout in 'execution of /etc/xen/scripts/block add'

  - bsc#1029827: Forward port xenstored

  - bsc#1029128: Make xen to really produce xen.efi with gcc48
