The remote host is missing an update to the system as announced in the referenced advisory FreeBSD-SA-08:13.protosw.asc

The FreeBSD kernel provides support for a variety of different types of communications sockets, including IPv4, IPv6, ISDN, ATM, routing protocol, link-layer, netgraph(4), and bluetooth sockets. As an early form of object-oriented design, much of the functionality specific to different types of sockets is abstracted via function pointers. Some function pointers for netgraph and bluetooth sockets are not properly initialized.
