IPv6 Type 0 Route Headers allow the sender to control packet routing. This vulnerability may allow an attacker to cause a denial-of-service condition.
Routing header options provided by IPv6 allow packet senders to indicate specific nodes through which the packet should travel. Note that a node is defined as any device that implements IPv6, which includes hosts as well as routing devices. According to FreeBSD-SA-07:03.ipv6:
An attacker can "amplify" a denial of service attack against a link between two vulnerable hosts; that is, by sending a small volume of traffic the attacker can consume a much larger amount of bandwidth between the two vulnerable hosts.
This condition can facilitate a number of different impacts including packet amplification, bypassing filtering devices, denial of service, and defeating IPv6 Anycast.
