   An update that solves 5 vulnerabilities and has four fixes
   is now available.

Description:


   This update for xen 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-2016-9603: A privileged user within the guest VM can cause a heap
     overflow in the device model process, potentially escalating their
     privileges to that of the device model process (bsc#1028655).
   - CVE-2017-6414: Memory leak in the vcard_apdu_new function in card_7816.c
     in libcacard allowed local guest OS users to cause a denial of service
     (host memory consumption) via vectors related to allocating a new APDU
     object (bsc#1027570).
   - 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).
   - CVE-2017-2633: The VNC display driver support was vulnerable to an
     out-of-bounds memory access issue. A user/process inside guest could use
     this flaw to cause DoS (bsc#1026636).

   These non-security issues were fixed:

   - bsc#1022555: Timeout in "execution of /etc/xen/scripts/block add"
   - bsc#1029827: Forward port xenstored
