These security issues were fixed:
- Page transfer might have allowed PV guest to elevate privilege (XSA-217,
 bsc#1042882)
- Races in the grant table unmap code allowed for informations leaks and
 potentially privilege escalation (XSA-218, bsc#1042893)
- Insufficient reference counts during shadow emulation allowed a
 malicious pair of guest to elevate their privileges to the privileges
 that XEN runs under (XSA-219, bsc#1042915)
- Missing NULL pointer check in event channel poll allows guests to DoS
 the host (XSA-221, bsc#1042924)
- Stale P2M mappings due to insufficient error checking allowed malicious
 guest to leak information or elevate privileges (XSA-222, bsc#1042931)
- Grant table operations mishandled reference counts allowing malicious
 guests to escape (XSA-224, bsc#1042938)
- CVE-2017-9330: USB OHCI Emulation in qemu allowed local guest OS users
 to cause a denial of service (infinite loop) by leveraging an incorrect
 return value (bsc#1042160)
- CVE-2017-8309: Memory leak in the audio/audio.c allowed remote attackers
 to cause a denial of service (memory consumption) by repeatedly starting
 and stopping audio capture (bsc#1037243)
- PKRU and BND* leakage between vCPU-s might have leaked information to
 other guests (XSA-220, bsc#1042923)
These non-security issues were fixed:
- bsc#1027519: Included various upstream patches
- bsc#1035642: Ensure that rpmbuild works");
