   An update that solves 6 vulnerabilities and has 9 fixes is
   now available.

Description:


   This update for xen fixes several issues.

   These security issues were fixed:

   - A malicious 64-bit PV guest may be able to access all of system memory,
     allowing for all of privilege escalation, host crashes, and information
     leaks by placing a IRET hypercall in the middle of a multicall batch
     (XSA-213, bsc#1034843)
   - A malicious pair of guests may be able to access all of system memory,
     allowing for all of privilege escalation, host crashes, and information
     leaks because of a missing check when transfering pages via
     GNTTABOP_transfer (XSA-214, bsc#1034844).
   - CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local guest OS
     privileged users to cause a denial of service (out-of-bounds read and
     QEMU process crash) via vectors related to copying VGA data via the
     cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_ functions
     (bsc#1034994).
   - CVE-2016-9603: A privileged user within the guest VM could have caused a
     heap overflow in the device model process, potentially escalating their
     privileges to that of the device model process (bsc#1028655)

   These non-security issues were fixed:

   - bsc#1027519: Missing upstream bug fixes
   - bsc#1015348: libvirtd does not start during boot
   - bsc#1022555: Timeout in "execution of /etc/xen/scripts/block add
