CVE-2008-5716 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-5716):
  xend in Xen 3.3.0 does not properly restrict a guest VM's write
  access within the /local/domain xenstore directory tree, which allows
  guest OS users to cause a denial of service and possibly have
  unspecified other impact by writing to (1) console/tty, (2)
  console/limit, or (3) image/device-model-pid.  NOTE: this issue
  exists because of erroneous set_permissions calls in the fix for
  CVE-2008-4405.
