This update for xen fixes several issues.
These security issues were fixed :
CVE-2017-10912: Page transfer might have allowed PV guest to elevate privilege (XSA-217, bsc#1042882)
CVE-2017-10913 CVE-2017-10914: Races in the grant table unmap code allowed for informations leaks and potentially privilege escalation (XSA-218, bsc#1042893)
CVE-2017-10915: 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)
CVE-2017-10917: Missing NULL pointer check in event channel poll allows guests to DoS the host (XSA-221, bsc#1042924)
CVE-2017-10918: Stale P2M mappings due to insufficient error checking allowed malicious guest to leak information or elevate privileges (XSA-222, bsc#1042931)
CVE-2017-10920, CVE-2017-10921, CVE-2017-10922: 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
