Exploitation requires network reachability to bgpd (TCP/179) and the ability to send crafted BGP messages as a configured peer, which substantially limits exposure to systems intentionally peering BGP. Hosts that do not run Quagga bgpd or have no configured BGP neighbors are not affected, so this can be safely deprioritized.",
