  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 non-security issue was fixed:

  - Fix qemu-guest-agent uninstall (boo#1093169)

  Patch Instructions:

  To install this openSUSE Security Update use the SUSE recommended
  installation methods
  like YaST online_update or 'zypper patch'.

  Alternatively you can run the command listed for your product:

  - openSUSE Leap 15.0:

  zypper in -t patch openSUSE-2018-603=1");

  script_tag(name:"affected", value:"qemu on openSUSE Leap 15.0.");

  script_tag(name:"solution", value:"Please install the updated package(s).");

  script_tag(name:"solution_type", value:"VendorFix");
