FreeBSD -- routed(8) remote denial of service vulnerability

Problem Description:
The input path in routed(8) will accept queries from any
source and attempt to answer them. However, the output path
assumes that the destination address for the response is
on a directly connected network.
Impact:
Upon receipt of a query from a source which is not on a
directly connected network, routed(8) will trigger an
assertion and terminate. The affected system’s routing table
will no longer be updated. If the affected system is a
router, its routes will eventually expire from other routers’
routing tables, and its networks will no longer be reachable
unless they are also connected to another router.
