{"id":"UBUNTU-CVE-2019-10167","details":"The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an \"emulatorbin\" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.","modified":"2026-02-04T04:07:17.322953Z","published":"2019-06-20T00:00:00Z","related":["USN-4047-1"],"upstream":["CVE-2019-10167"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-10167"},{"type":"REPORT","url":"https://rhn.redhat.com/errata/RHSA-2019-1579.html"},{"type":"REPORT","url":"https://access.redhat.com/libvirt-privesc-vulnerabilities"},{"type":"REPORT","url":"https://security.libvirt.org/2019/0006.html"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4047-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-10167"}],"affected":[{"package":{"name":"libvirt","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libvirt@1.3.1-1ubuntu10.27?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.3.1-1ubuntu10.27"}]}],"versions":["1.2.16-2ubuntu11","1.2.16-2ubuntu12","1.2.16-2ubuntu13","1.2.16-2ubuntu14","1.2.21-2ubuntu1","1.2.21-2ubuntu3","1.2.21-2ubuntu4","1.2.21-2ubuntu5","1.2.21-2ubuntu7","1.2.21-2ubuntu8","1.2.21-2ubuntu9","1.2.21-2ubuntu10","1.3.1-1ubuntu1","1.3.1-1ubuntu2","1.3.1-1ubuntu3","1.3.1-1ubuntu4","1.3.1-1ubuntu6","1.3.1-1ubuntu9","1.3.1-1ubuntu10","1.3.1-1ubuntu10.1","1.3.1-1ubuntu10.2","1.3.1-1ubuntu10.3","1.3.1-1ubuntu10.5","1.3.1-1ubuntu10.6","1.3.1-1ubuntu10.7","1.3.1-1ubuntu10.8","1.3.1-1ubuntu10.10","1.3.1-1ubuntu10.11","1.3.1-1ubuntu10.12","1.3.1-1ubuntu10.13","1.3.1-1ubuntu10.14","1.3.1-1ubuntu10.15","1.3.1-1ubuntu10.17","1.3.1-1ubuntu10.18","1.3.1-1ubuntu10.19","1.3.1-1ubuntu10.21","1.3.1-1ubuntu10.22","1.3.1-1ubuntu10.23","1.3.1-1ubuntu10.24","1.3.1-1ubuntu10.25","1.3.1-1ubuntu10.26"],"ecosystem_specific":{"binaries":[{"binary_name":"libvirt-bin","binary_version":"1.3.1-1ubuntu10.27"},{"binary_name":"libvirt-dev","binary_version":"1.3.1-1ubuntu10.27"},{"binary_name":"libvirt0","binary_version":"1.3.1-1ubuntu10.27"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-10167.json"}},{"package":{"name":"libvirt","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libvirt@4.0.0-1ubuntu8.12?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.0.0-1ubuntu8.12"}]}],"versions":["3.6.0-1ubuntu5","3.6.0-1ubuntu6","4.0.0-1ubuntu1","4.0.0-1ubuntu2","4.0.0-1ubuntu3","4.0.0-1ubuntu4","4.0.0-1ubuntu5","4.0.0-1ubuntu6","4.0.0-1ubuntu7","4.0.0-1ubuntu8","4.0.0-1ubuntu8.1","4.0.0-1ubuntu8.2","4.0.0-1ubuntu8.3","4.0.0-1ubuntu8.4","4.0.0-1ubuntu8.5","4.0.0-1ubuntu8.6","4.0.0-1ubuntu8.7","4.0.0-1ubuntu8.8","4.0.0-1ubuntu8.9","4.0.0-1ubuntu8.10","4.0.0-1ubuntu8.11"],"ecosystem_specific":{"binaries":[{"binary_name":"libnss-libvirt","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-bin","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-clients","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon-driver-storage-gluster","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon-driver-storage-rbd","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon-driver-storage-sheepdog","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon-driver-storage-zfs","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-daemon-system","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-dev","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-sanlock","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt-wireshark","binary_version":"4.0.0-1ubuntu8.12"},{"binary_name":"libvirt0","binary_version":"4.0.0-1ubuntu8.12"}],"availability":"No subscription required"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-10167.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
