Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote attackers to cause a denial of service (daemon crash) via a Link State Update (aka LS Update) packet containing a network-LSA link-state advertisement for which the data-structure length is smaller than the value in the Length header field.

Security readout for executives and security teams

This flaw can let an attacker crash Quagga's OSPF routing daemon by sending a malformed OSPFv2 routing update. The main business risk is routing instability or loss of routing service on systems still running vulnerable Quagga ospfd versions before 0.99.20.1. Exposure is limited to environments running Quagga ospfd before 0.99.20.1 and accepting OSPFv2 traffic. Risk is highest on routing segments where untrusted or compromised systems can send OSPF packets to the daemon. Prioritize remediation for routers or network appliances using Quagga ospfd on production routing paths. This is primarily an availability risk, but routing service crashes can affect critical connectivity. Mitigation focus: Upgrade Quagga to 0.99.20.1 or later where applicable.; Apply vendor security updates from Red Hat, Fedora, or Debian advisories.; Restrict OSPFv2 traffic to trusted routing peers and segments..
