"Xen has been updated to version 4.2.5 with additional patches to fix
six security issues :

  - Guest effectable 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#903850)

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

  - Insufficient restrictions on certain MMU update
    hypercalls (CVE-2014-8594). These non-security issues
    have been fixed :

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

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

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

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