  script_tag(name:"insight", value:"ipfw(8) is a system facility which provides IP packet filtering,
accounting, and redirection. Among the many features, while discarding
packets it can perform actions defined by the user, such as sending
back TCP reset or ICMP unreachable packets. These operations can be
performed by using the reset, reject or uncreach actions.

The firewall maintains a pointer to layer 4 header information in the
event that it needs to send a TCP reset or ICMP error message to
discard packets.  Due to incorrect handling of IP fragments, this
pointer fails to get initialized.");
