According to its self-reported version number, the installation of Quagga’s BGP daemon listening on the remote host is affected by multiple denial of service vulnerabilities :

  • A denial of service vulnerability can be triggered by a malformed OPEN message from an explicitly configured BGP peer.

  • A denial of service vulnerability can be triggered by a malformed COMMUNITY attribute from an explicitly configured BGP peer, when the daemon has debugging enabled.
