Description:

   This update for libvirt 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 Sampling (MLPDS)
   - CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory
     (MDSUM)

   These updates contain the libvirt adjustments, that pass through the new
   'md-clear' CPU flag (bsc#1135273).
