This update for xen to version 4.7.2 fixes the following issues:

These security issues were fixed:

- CVE-2017-7228: Broken check in memory_exchange() permited 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
