Security Vulnerabilities of IPv6 Tunnels

This article talks about novel security vulnerabilities of IPv6 tunnel – an important type of migration mechanisms from IPv4 to IPv6 im plemented by all major operating systems and routers. The vulner abilities allow an attacker to form routing loops which can easily pro duce DoS attacks. Gabi will describe the principles of the attack and then demonstrate how to actually implement it. These vulnerabilitie were first presented at Usenix W00T ’09 in the paper I co-authored with Michael Arov.
