Descriptions

When libvirtd is configured by OSP director (tripleo-heat-templates) to use the TLS transport it defaults to the same certificate authority as all non-libvirtd services. As no additional authentication is configured this allows these services to connect to libvirtd (which is equivalent to root access). If a vulnerability exists in another service it could, combined with this flaw, be exploited to escalate privileges to gain control over compute nodes.

Cuando libvirtd es configurado por OSP director (tripleo-heat-templates) para usar el transporte TLS, vuelve por defecto a la misma autoridad de certificado que todos los servicios que no pertenecen a libvirtd. Como no se configura autenticación adicional, esto permite que esos servicios se conecten a libvirtd (lo que equivale al acceso root). Si existe una vulnerabilidad en otro servicio podría, combinado con este error, explotarse para escalar privilegios y tomar el control de los nodos de cálculo.
