   An update that solves 12 vulnerabilities and has one errata
   is now available.

Description:


   The SUSE Linux Enterprise Server 11 Service Pack 3 Xen
   hypervisor and  toolset has been updated to 4.2.4 to fix
   various bugs and security issues:

   The following security issues have been addressed:

   *

   XSA-60: CVE-2013-2212: The vmx_set_uc_mode function
   in Xen 3.3 through 4.3, when disabling chaches, allows
   local HVM guests with access to memory mapped I/O regions
   to cause a denial of service (CPU consumption and possibly
   hypervisor or guest kernel panic) via a crafted GFN range.
   (bnc#831120)

   *

   XSA-80: CVE-2013-6400: Xen 4.2.x and 4.3.x, when
   using Intel VT-d and a PCI device has been assigned, does
   not clear the flag that suppresses IOMMU TLB flushes when
   unspecified errors occur, which causes the TLB entries to
   not be flushed and allows local guest administrators to
   cause a denial of service (host crash) or gain privileges
   via unspecified vectors. (bnc#853048)

   *

   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-83: CVE-2014-1642: The IRQ setup in Xen 4.2.x and
   4.3.x, when using device passthrough and configured to
   support a large number of CPUs, frees certain memory that
   may still be intended for use, which allows local guest
   administrators to cause a denial of service (memory
   corruption and hypervisor crash) and possibly execute
   arbitrary code via vectors related to an out-of-memory
   error that triggers a (1) use-after-free or (2) double
   free. (bnc#860092)

   *

   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-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 aribitrary guests.
   (bnc#860163)

   *

   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-85: CVE-2014-1895: The FLASK_AVC_CACHESTAT
   hypercall, which provides access to per-cpu statistics on
   the Flask security policy, incorrectly validates the CPU
   for which statistics are being requested. (bnc#860165)

   *

   XSA-86: CVE-2014-1896: libvchan (a library for
   inter-domain communication) does not correctly handle
   unusual or malicious contents in the xenstore ring. A
   malicious guest can exploit this to cause a libvchan-using
   facility to read or write past the end of the ring.
   (bnc#860300)

   *

   XSA-87: CVE-2014-1666: The do_physdev_op function in
   Xen 4.1.5, 4.1.6.1, 4.2.2 through 4.2.3, and 4.3.x does not
   properly restrict access to the (1) PHYSDEVOP_prepare_msix
   and (2) PHYSDEVOP_release_msix operations, which allows
   local PV guests to cause a denial of service (host or guest
   malfunction) or possibly gain privileges via unspecified
   vectors. (bnc#860302)

   *

   XSA-88: CVE-2014-1950: Use-after-free vulnerability
   in the xc_cpupool_getinfo function in Xen 4.1.x through
   4.3.x, when using a multithreaded toolstack, does not
   properly handle a failure by the xc_cpumap_alloc function,
   which allows local users with access to management
   functions to cause a denial of service (heap corruption)
   and possibly gain privileges via unspecified vectors.
   (bnc#861256)

   Also the following non-security bugs have been fixed:

   * Fixed boot problems with Xen kernel. "(XEN) setup
   0000:00:18.0 for d0 failed (-19)" (bnc#858311)
   * Fixed Xen hypervisor panic on 8-blades nPar with
   46-bit memory addressing. (bnc#848014)
   * Fixed Xen hypervisor panic in HP's UEFI x86_64
   platform and with xen environment, in booting stage.
   (bnc#833251)
   * xend/pvscsi: recognize also SCSI CDROM devices
   (bnc#863297)
   * pygrub: Support (/dev/xvda) style disk specifications
