   An update that solves two vulnerabilities and has 9 fixes
   is now available.

Description:

   This update for xen fixes several issues.

   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
