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

Description:

   This update for xen to version 4.7.4 (bsc#1027519) fixes several issues.

   This new feature was added:

   – Support migration of HVM domains larger than 1 TB

   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).

   This non-security issue was fixed:

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