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 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.
