Abstract:
This memo documents two scenarios in which an on-link attacker emits
a crafted IPv6 Neighbor Discovery (ND) packet that poisons its
victim's neighbor cache. In the first scenario, the attacker causes
a victim to map a local IPv6 address to a local router's own link-
layer address. In the second scenario, the attacker causes the
victim to map a unicast IP address to a link layer broadcast address.
In both scenarios, the attacker can exploit the poisoned neighbor
cache to perform a subsequent forwording-loop attack, thus
potentially causing a Denial of Service.
Finally, this memo specifies simple validations that the recipient of
an ND message can execute in order to protect itself against the
above-mentioned threats.
