     (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:

     (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
