  <description>This update for xen fixes the following security issues:

- 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).
