*yawn* No news, move along, nothing to see. RFC4862, section 6: The use of stateless address autoconfiguration and Duplicate Address Detection opens up the possibility of several denial-of-service attacks. For example, any node can respond to Neighbor Solicitations for a tentative address, causing the other node to reject the address as a duplicate. A separate document [RFC3756] discusses details about these attacks, which can be addressed with the Secure Neighbor Discovery protocol [RFC3971]. It should also be noted that [RFC3756] points out that the use of IP security is not always feasible depending on network environments. Note that similar text was present in RFC2462, all the way back in Dec 1998. So somebody's 13 years late to the party.
