  These security issues were fixed:

  - Guest affectable page reference leak in MMU_MACHPHYS_UPDATE handling
  (CVE-2014-9030).

  - Insufficient bounding of 'REP MOVS' to MMIO emulated inside the
  hypervisor (CVE-2014-8867).

  - Excessive checking in compatibility mode hypercall argument translation
  (CVE-2014-8866).

  - Guest user mode triggerable VM exits not handled by hypervisor
  (bnc#9038500).

  - Missing privilege level checks in x86 emulation of far branches
  (CVE-2014-8595).

  - Insufficient restrictions on certain MMU update hypercalls
  (CVE-2014-8594).

  - Long latency virtual-mmu operations are not preemptible (CVE-2014-5146,
  CVE-2014-5149).

  - Intel VT-d Interrupt Remapping engines can be evaded by native NMI
  interrupts  (CVE-2013-3495).

  These non-security issues were fixed:

  - Corrupted save/restore test leaves orphaned data in xenstore
  (bnc#903357).

  - Temporary migration name is not cleaned up after migration (bnc#903359).

  - Xen save/restore of HVM guests cuts off disk and networking
  (bnc#866902).

  - increase limit domUloader to 32MB (bnc#901317).

  - XEN Host crashes when assigning non-VF device (SR-IOV) to guest
  (bnc#898772).

  - Windows 2012 R2 fails to boot up with greater than 60 vcpus (bnc#882089).

  - Restrict requires on grub2-x86_64-xen to x86_64 hosts

  - Change default dump directory (bsc#900292).

  - Update xen2libvirt.py to better detect and handle file formats

  - libxc: check return values on mmap() and madvise() on
  xc_alloc_hypercall_buffer() (bnc#897906).

  - Bug `xen-tools` uninstallable  grub2-x86_64-xen dependency not available
  (bnc#897614).

  - Adjust xentop column layout (bnc#896023).");
