Descriptions

The LXC driver (lxc/lxc_driver.c) in libvirt 1.0.1 through 1.2.1 allows local users to (1) delete arbitrary host devices via the virDomainDeviceDettach API and a symlink attack on /dev in the container; (2) create arbitrary nodes (mknod) via the virDomainDeviceAttach API and a symlink attack on /dev in the container; and cause a denial of service (shutdown or reboot host OS) via the (3) virDomainShutdown or (4) virDomainReboot API and a symlink attack on /dev/initctl in the container, related to "paths under /proc/$PID/root" and the virInitctlSetRunLevel function.

El controlador LXC (lxc/lxc_driver.c) en libvirt 1.0.1 hasta 1.2.1 permite a usuarios locales (1) borrar dispositivos arbitrarios a través de API virDomainDeviceDettach y un ataque symlink en /dev en el contenedor; (2) crear nodos arbitrarios (mknod) a través de la API virDomainDeviceAttach y un ataque symlink en /dev en el contenedor; y causar una denegación de servicio (apagado o reinicio del sistema operativo del host) a través de (3) virDomainShutdown o (4) virDomainReboot API y a un ataque symlink en /dev/initctl en el contenedor, relacionado con "rutas contenidas en /proc/$PID/root" y la función virInitctlSetRunLevel.
