  script_tag(name:"insight", value:"xen was updated to fix nine security issues.

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).");
