FreeBSD : FreeBSD -- routed(8) remote denial of service vulnerability (0d584493-600a-11e6-a6c3-14dae9d210b8)

medium Nessus Plugin ID 92893

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

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.

Solution

Update the affected packages.
