CVE-2019-10161

Red Hat statement

* This vulnerability requires access to the libvirt socket, normally in /var/run/libvirt/libvirt_sock_ro. Typically in hypervisor environments, local user accounts are not supported so no untrusted users should be able to access this socket. * Red Hat Gluster Storage 3 is not affected by this vulnerability as libvirtd daemon is not shipped in Gluster. * On Red Hat Enterprise Linux 6, the impact of this vulnerability is limited to denial of service or disclosing the existence of arbitrary files. Privilege escalation is not possible. For RHEL6, this CVE is rated as Moderate severity with 7.3/CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:H

Red Hat mitigation

The Unix permissions of libvirt's read-only socket can be made more restrictive than the default (0777) by editing `/etc/libvirt/libvirtd.conf`. The settings `unix_sock_group = libvirt` and `unix_sock_ro_perms = 0770` will restrict access to only members of `libvirt`, who already have management access to virtual machines.
