______________________________________________________________________________

   An update that solves one vulnerability and has one errata
   is now available.

Description:

   This update for qemu fixes several issues.

   This security issue was fixed:

   - CVE-2018-3639: Spectre v4 vulnerability mitigation support for KVM
     guests (bsc#1092885).

     Systems with microprocessors utilizing speculative execution and
   speculative execution of memory reads before the addresses of all prior
   memory writes are known may allow unauthorized disclosure of information
   to an attacker with local user access via a side-channel analysis.

     This patch permits the new x86 cpu feature flag named "ssbd" to be
   presented to the guest, given that the host has this feature, and KVM
   exposes it to the guest as well.

     For this feature to be enabled please use the qemu commandline
     -cpu $MODEL,+spec-ctrl,+ssbd so the guest OS can take advantage of the
      feature.

     spec-ctrl and ssbd support is also required in the host.

   This feature was added:

   - Add support for block resize support for xen disks through the monitor

   This non-security issue was fixed:

   - bsc#1079405: Add new look up path "sys/class/tpm" for tpm cancel path
     based
     on Linux 4.0 change
