The remote Amazon Linux AMI host is missing a security update.
The bgp_capability_orf function in bgpd in Quagga 0.99.20.1 and
earlier allows remote attackers to cause a denial of service
(assertion failure and daemon exit) by leveraging a BGP peering
relationship and sending a malformed Outbound Route Filtering (ORF)
capability TLV in an OPEN message.
