CVE-2017-17046 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-17046):
  An issue was discovered in Xen through 4.9.x on the ARM platform allowing
  guest OS users to obtain sensitive information from DRAM after a reboot,
  because disjoint blocks, and physical addresses that do not start at zero,
  are mishandled.

CVE-2017-17045 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-17045):
  An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to
  gain privileges on the host OS, obtain sensitive information, or cause a
  denial of service (BUG and host OS crash) by leveraging the mishandling of
  Populate on Demand (PoD) Physical-to-Machine (P2M) errors.

CVE-2017-17044 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-17044):
  An issue was discovered in Xen through 4.9.x allowing HVM guest OS users to
  cause a denial of service (infinite loop and host OS hang) by leveraging the
  mishandling of Populate on Demand (PoD) errors.
