OpenPKG Security Advisory – A Denial of Service (DoS) vulnerability exists in the routing daemon Quagga, versions up to and including 0.99.6. The Quagga bgpd(8) daemon is vulnerable as configured peers may cause it to abort because of an assertion which can be triggered by peers by sending an “UPDATE” message with a specially crafted, malformed Multi-Protocol reachable/unreachable “NLRI” attribute.
