            June 30, 2004 - Adam Osuchowski posted a bug about remote DoS vulnerability in Linux kernel 2.6.x. Please see

            http://www.netfilter.org/security/2004-06-30-2.6-tcpoption.html for more informations. My firewall system doesn't use the "--tcp-option", so all releases (0.4.9-1 - 0.5.0) can be used without fixing iptables. I want to thank all people who use jsfirewall.
