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

Description:

   This update for xen fixes several issues.

   These security issues were fixed:

   - bsc#1068187: Failure to recognize errors in the Populate on Demand (PoD)
     code allowed for DoS (XSA-246)
   - bsc#1068191: Missing p2m error checking in PoD code allowed unprivileged
     guests to retain a writable mapping of freed memory leading to
     information leaks, privilege escalation or DoS (XSA-247).
   - CVE-2017-15289: The mode4and5 write functions allowed local OS guest
     privileged users to cause a denial of service (out-of-bounds write
     access and Qemu process crash) via vectors related to dst calculation
     (bsc#1063123)
   - CVE-2017-15597: A grant copy operation being done on a grant of a dying
     domain allowed a malicious guest administrator to corrupt hypervisor
     memory, allowing for DoS or potentially privilege escalation and
     information leaks (bsc#1061075).
   - CVE-2017-15595: x86 PV guest OS users were able to cause a DoS
     (unbounded recursion, stack consumption, and hypervisor crash) or
     possibly gain privileges via crafted page-table stacking (bsc#1061081).
   - CVE-2017-15592: x86 HVM guest OS users were able to cause a DoS
     (hypervisor crash) or possibly gain privileges because self-linear
     shadow mappings were mishandled for translated guests (bsc#1061086).
   - CVE-2017-13672: The VGA display emulator support allowed local guest OS
     privileged users to cause a denial of service (out-of-bounds read and
     QEMU process crash) via vectors involving display update (bsc#1056336)

   This non-security issue was fixed:

   - bsc#1055047: Fixed --initrd-inject option in virt-install
