Watchguard SOHO remote denial of service vulnerability - All versions prior to v5.0.35 crash when tcp traffic with bad IP options are sent. The Watchguard Soho firewall does not perform parsing of IP options unless the packet has to be forwarded. This means that most home users will not be affected by this vulnerability, unless they have a service running behind the firewall, that is enabled through port- forwarding (eg. FTP, HTTP).
