The BGP daemon (bgpd) in Quagga 0.99.11 and earlier allows remote attackers to cause a denial of service (crash) via an AS path containing ASN elements whose string representation is longer than expected, which triggers an assert error.

Security readout for executives and security teams

This flaw can crash Quagga's BGP daemon when it processes an AS path with unusually long ASN string elements. For organizations using affected Quagga versions for routing, the business risk is loss of BGP routing service, not data theft. Exposure is limited to systems running Quagga bgpd 0.99.11 or earlier, especially routing hosts that accept BGP updates from peers. The bundle does not identify other affected products. Prioritize if Quagga bgpd supports production routing or external BGP peering. Treat as lower urgency for systems without bgpd enabled or without BGP exposure. Mitigation focus: Inventory systems running Quagga bgpd and identify versions 0.99.11 or earlier.; Apply fixed Quagga packages from relevant vendor advisories where available.; Review Ubuntu, Debian, Mandriva, Fedora, or SUSE guidance for distribution-specific fixes..
