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.
