Package : libvirt
CVE ID : CVE-2019-10161 CVE-2019-10167

Two vulnerabilities were discovered in Libvirt, a virtualisation
abstraction library, allowing an API client with read-only permissions
to execute arbitrary commands via the virConnectGetDomainCapabilities
API, or read or execute arbitrary files via the
virDomainSaveImageGetXMLDesc API.

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.
