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.
