Security update for xen

This update for xen fixes the following issues:

This security issue was fixed:

  • CVE-2018-3646: Systems with microprocessors utilizing speculative execution and address translations may have allowed unauthorized disclosure of information residing in the L1 data cache to an attacker with local user access with guest OS privilege via a terminal page fault and a side-channel analysis (bsc#1091107, bsc#1027519).

These non-security issues were fixed:

  • bsc#1102116: SSBD is not virtualized for guests
  • bsc#1092631: Preserve the xl dmesg output after boot for determining what speculative mitigations have been detected by the hypervisor.
  • bsc#1101684: Make xen able to disable the visibility of the new CPU flags.
