    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
    - 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
