VPN traffic leaks in IPv6/IPv4 dual-stack networks/hosts
FYI. This is might affect NetBSD users employing e.g. OpenVPN:
For a project such as OpenVPN, a (portable) fix might be non-trivial.
However, I guess NetBSD might hook some PF rules when establishing the
VPN tunnel, such that e.g. all v6 traffic is filtered (yes, this is
certainly not the most desirable fix, but still probably better than
having your supposedly-secured traffic being sent in the clear).
P.S.: Please check the corresponding thread (same "Subject") on the
tech%openbsd.org@localhost mailing-list, since they have some patches for some
