OpenBSD 3.9 and 4.0 have fixed an issue to correct a problem in the IPv6 stack.
Source code patches are available at:
# vi /etc/pf.conf
Add a line:# pfctl -f /etc/pf.conf
To load the new rules in the pf packet filter# pfctl -s rules
Check the rule got loaded in the runtime rules.The workaround does disable all incoming IPv6 packets on the machine.
The patch itself is a kernel patch, so you will need to recompile a kernel, install it and reboot the affected machines.
