Additionally the libvirt's cpu map was updated to make addressing CVE-2018-3639, CVE-2017-5753, CVE-2017-5715, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130 and CVE-2019-11091 easier by supporting the md-clear, ssbd, spec-ctrl and ibpb CPU features when picking CPU models without having to fall back to host-passthrough.

For the stable distribution (stretch), these problems have been fixed in version 3.0.0-4+deb9u4.

We recommend that you upgrade your libvirt packages.

For the detailed security status of libvirt please refer to its security tracker page at: [link moved to references]");
