The remote host is missing a security update.
This security update fixes the remote DoS possibility identified and fixed by Adam Osuchowski and Tomasz Dubinski in the netfilter code of the 2.6 kernel. Note that this remote DoS can only be triggered when using the rarely used '-p tcp --tcp-option' options in the netfilter firewall subsystem. Fedora Core 2 systems are not vulnerable unless the administrator manually configured this rarely used option.
Update the affected package(s).
