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");
