*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.
For more information, see RFC 6104 for a comprehensive problem
statement (rogue routers), and RFC 6105 for a proposed solution.
