The ospf6_lsa_is_changed function in ospf6_lsa.c in the OSPFv3 implementation in ospf6d in Quagga before 0.99.19 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via trailing zero values in the Link State Advertisement (LSA) header list of an IPv6 Database Description message.

Security readout for executives and security teams

This flaw can crash Quagga's OSPFv3 routing daemon when it receives a malformed IPv6 routing protocol message. The business impact is availability: affected routers or hosts may lose OSPFv3 routing until the daemon restarts or is repaired. Exposure is limited to systems running Quagga ospf6d with OSPFv3 enabled, especially versions before 0.99.19 or older distribution packages identified by vendor advisories. Treat as a targeted availability risk for legacy IPv6 routing environments. Prioritize if Quagga OSPFv3 supports production routing or sensitive network segments. Mitigation focus: Upgrade Quagga to 0.99.19 or a vendor package containing the fix.; Check Debian, Red Hat, SUSE, and Gentoo advisories for distribution-specific packages.; Restart affected ospf6d services after patching if the vendor procedure requires it..
