Title : Virtual Private Network (VPN) traffic leakages in
dual-stack hosts/ networks

Abstract:
The subtle way in which the IPv6 and IPv4 protocols co-exist in
typical networks, together with the lack of proper IPv6 support in
popular Virtual Private Network (VPN) products, may inadvertently
result in VPN traffic leaks. That is, traffic meant to be
transferred over a VPN connection may leak out of such connection and
be transferred in the clear from the local network to the final
destination. This document discusses some scenarios in which such
VPN leakages may occur, either as a side effect of enabling IPv6 on a
local network, or as a result of a deliberate attack from a local
attacker. Additionally, it discusses possible mitigations for the
aforementioned issue.
