  hypervisor and  toolset have been updated to fix various
  security issues and some bugs.

  The following security issues have been addressed:

  *

  XSA-84: CVE-2014-1894: Xen 3.2 (and presumably
  earlier) exhibit both problems with the overflow issue
  being present for more than just the suboperations listed
  above. (bnc#860163)

  *

  XSA-84: CVE-2014-1892 CVE-2014-1893: Xen 3.3 through
  4.1, while not affected by the above overflow, have a
  different overflow issue on FLASK_{GET, SET}BOOL and expose
  unreasonably large memory allocation to arbitrary guests.
  (bnc#860163)

  *

  XSA-84: CVE-2014-1891: The FLASK_{GET, SET}BOOL,
  FLASK_USER and FLASK_CONTEXT_TO_SID suboperations of the
  flask hypercall are vulnerable to an integer overflow on
  the input size. The hypercalls attempt to allocate a buffer
  which is 1 larger than this size and is therefore
  vulnerable to integer overflow and an attempt to allocate
  then access a zero byte buffer. (bnc#860163)

  *

  XSA-82: CVE-2013-6885: The microcode on AMD 16h 00h
  through 0Fh processors does not properly handle the
  interaction between locked instructions and write-combined
  memory types, which allows local users to cause a denial of
  service (system hang) via a crafted application, aka the
  errata 793 issue. (bnc#853049)

  *

  XSA-76: CVE-2013-4554: Xen 3.0.3 through 4.1.x
  (possibly 4.1.6.1), 4.2.x (possibly 4.2.3), and 4.3.x
  (possibly 4.3.1) does not properly prevent access to
  hypercalls, which allows local guest users to gain
  privileges via a crafted application running in ring 1 or
  2. (bnc#849668)

  *

  XSA-74: CVE-2013-4553: The XEN_DOMCTL_getmemlist
  hypercall in Xen 3.4.x through 4.3.x (possibly 4.3.1) does
  not always obtain the page_alloc_lock and mm_rwlock in the
  same order, which allows local guest administrators to
  cause a denial of service (host deadlock). (bnc#849667)

  *

  XSA-73: CVE-2013-4494: Xen before 4.1.x, 4.2.x, and
  4.3.x does not take the page_alloc_lock and
  grant_table.lock in the same order, which allows local
  guest administrators with access to multiple vcpus to cause
  a denial of service (host deadlock) via unspecified
  vectors. (bnc#848657)

  *

  XSA-67: CVE-2013-4368: The outs instruction emulation
  in Xen 3.1.x, 4.2.x, 4.3.x, and earlier, when using FS: or
  GS: segment override, uses an uninitialized variable as a
  segment base, which allows local 64-bit PV guests to obtain
  sensitive information (hypervisor stack content) via
  unspecified vectors related to stale d ...
