  - 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).

  - Missing privilege level checks in x86 HLT, LGDT, LIDT,
    and LMSW emulation (CVE-2014-7155).

  - Hypervisor heap contents leaked to guests
    (CVE-2014-4021).

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

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

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

  - Missing privilege level checks in x86 emulation of
    software interrupts (CVE-2014-7156).

  - Race condition in HVMOP_track_dirty_vram
    (CVE-2014-7154).

  - Improper MSR range used for x2APIC emulation
    (CVE-2014-7188).

  - HVMOP_set_mem_type allows invalid P2M entries to be
    created (CVE-2014-3124).

  - HVMOP_set_mem_access is not preemptible (CVE-2014-2599).

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

  - Guest user mode triggerable VM exits not handled by
    hypervisor (bnc#903850).

The update package also includes non-security fixes. See advisory for
