Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2012-1820 medium priority: Ubuntu including 1 source packages (quagga), 6 status rows across 6 suites (hardy, lucid, natty, oneiric, precise, upstream): released 4, ignored 1, needs-triage 1.
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.
