       An update that solves four vulnerabilities and has three
       fixes is now available.
    
    Description:
    
       This update for xen fixes the following issues:
    
       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 Samling (MLPDS)
       - CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory
         (MDSUM)
    
       These updates contain the XEN Hypervisor adjustments, that additionaly
       also use CPU Microcode updates.
    
       The mitigation can be controlled via the "mds" commandline option, see the
       documentation.

       Other fixes:
    
       - 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.
