The OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (out-of-bounds memory access and daemon crash) via a Link State Update message with an invalid IPv6 prefix length.

Security readout for executives and security teams

CVE-2011-3323 is a denial-of-service flaw in Quagga's OSPFv3 daemon. A malformed routing update with an invalid IPv6 prefix length can crash ospf6d. The business risk is disruption to routing on systems still running vulnerable Quagga versions, especially legacy IPv6 routing environments. Exposure is most likely in legacy systems running Quagga ospf6d before 0.99.19 with OSPFv3 enabled. Actual reachability depends on who can deliver OSPFv3 Link State Update messages into the routing domain. Treat this as a legacy routing availability issue. Prioritize environments where Quagga still participates in IPv6 routing, because a daemon crash could interrupt route exchange and affect network stability. Mitigation focus: Upgrade Quagga to 0.99.19 or later where applicable.; Apply distribution security updates from Debian, Red Hat, SUSE, Gentoo, or the relevant vendor.; Inventory systems for Quagga ospf6d and OSPFv3 usage..
