A flaw was found in the way nfs-utils performed IP based authentication of mount requests. In configurations where a directory was exported to a group of systems using a DNS wildcard or NIS netgroup, an attacker could possibly gain access to other directories exported to a specific host or subnet, bypassing intended access restrictions.
