  Four new speculative execution information leak issues have been
  identified in Intel CPUs. (bsc#1111331)

  - CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS)

  - CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS)

  - CVE-2018-12130: Microarchitectural Load Port Data Sampling (MLPDS)

  - CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory
  (MDSUM)

  These updates contain the XEN Hypervisor adjustments, that additionally
  also use CPU Microcode updates.

  The mitigation can be controlled via the 'mds' commandline option, see the
  documentation.

  - Added code to change LIBXL_HOTPLUG_TIMEOUT at runtime.

  The included README has details about the impact of this change
  (bsc#1120095)

  - Fixes in Live migrating PV domUs

  An earlier change broke live migration of PV domUs without a device
  model. The migration would stall for 10 seconds while the domU was paused,
  which caused network connections to drop.  Fix this by tracking the need
  for a device model within libxl. (bsc#1079730, bsc#1098403, bsc#1111025)

  - Libvirt segfault when crash triggered on top of HVM guest (bsc#1120067)

  This update was imported from the SUSE:SLE-15:Update update project.

  Patch Instructions:

  To install this openSUSE Security Update use the SUSE recommended
  installation methods
  like YaST online_update or 'zypper patch'.

  Alternatively you can run the command listed for your product:

  - openSUSE Leap 15.0:

  zypper in -t patch openSUSE-2019-1403=1");

  script_tag(name:"affected", value:"'xen' package(s) on openSUSE Leap 15.0.");

  script_tag(name:"solution", value:"Please install the updated package(s).");

  script_tag(name:"solution_type", value:"VendorFix");
  script_tag(name:"qod_type", value:"package");
