CVE-2008-2931 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-2931):
  The do_change_type function in fs/namespace.c in the Linux kernel before
  2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability,
  which allows local users to gain privileges or cause a denial of service by
  modifying the properties of a mountpoint.
