teardown. This memory leak could -- over time -- exhaust the host's
memory.

A domain given partial management control via XEN_DOMCTL_max_vcpus can
mount a denial of service attack affecting the whole system. The
ability to also restart or create suitable domains is also required to
fully exploit the issue. Without this the leak is limited to a small
multiple of the maximum number of vcpus for the domain. The maximum
leak is 64kbytes per domain (re)boot (less on ARM)."

    allowed local users to cause a denial of service
    (instantiation failure) by creating /tmp/qemu-smb.*-*
    files before the program (bsc#932267).

  - CVE-2014-0222: Integer overflow in the qcow_open
    function allowed remote attackers to cause a denial of
    service (crash) via a large L2 table in a QCOW version 1
    image (bsc#877642).

  - CVE-2015-7835: Uncontrolled creation of large page
    mappings by PV guests (bsc#950367).

  - CVE-2015-7311: libxl in Xen did not properly handle the
    readonly flag on disks when using the qemu-xen device
    model, which allowed local guest users to write to a
    read-only disk image (bsc#947165).

  - CVE-2015-5239: Integer overflow in vnc_client_read() and
    protocol_client_msg() (bsc#944463).

  - CVE-2015-6815: With e1000 NIC emulation support it was
    possible to enter an infinite loop (bsc#944697).

  - CVE-2015-7969: Leak of main per-domain vcpu pointer
    array leading to denial of service (bsc#950703).

  - CVE-2015-7969: Leak of per-domain profiling- related
    vcpu pointer array leading to denial of service
    (bsc#950705).

  - CVE-2015-7971: Some pmu and profiling hypercalls log
    without rate limiting (bsc#950706).

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

critical security updates :

    should be rate-limited. In the xenoprof case, just like
    for XSA-146, include them only in debug builds. Since
    the vPMU code is rather new, allow them to be always
    present, but downgrade them to (rate limited) guest
    messages. This is XSA-152. (CVE-2015-7971)

  - xenoprof: free domain's vcpu array This was overlooked
    in fb442e2171 ('x86_64: allow more vCPU-s per guest').
    This is XSA-151. (CVE-2015-7969)

  - x86: guard against undue super page PTE creation When
    optional super page support got added (commit bd1cd81d64
    'x86: PV support for hugepages'), two adjustments were
    missed: mod_l2_entry needs to consider the PSE and RW
    bits when deciding whether to use the fast path, and the
    PSE bit must not be removed from L2_DISALLOW_MASK
    unconditionally. This is XSA-148.

    should be rate-limited. In the xenoprof case, just like
    for XSA-146, include them only in debug builds. Since
    the vPMU code is rather new, allow them to be always
    present, but downgrade them to (rate limited) guest
    messages. This is XSA-152. (CVE-2015-7971)

  - xenoprof: free domain's vcpu array This was overlooked
    in fb442e2171 ('x86_64: allow more vCPU-s per guest').
    This is XSA-151. (CVE-2015-7969)

  - x86: guard against undue super page PTE creation When
    optional super page support got added (commit bd1cd81d64
    'x86: PV support for hugepages'), two adjustments were
    missed: mod_l2_entry needs to consider the PSE and RW
