    Description:


    This update for xen fixes several security issues:

    - 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)
