Timbuktu Pro DoS

 
Timbuktu Pro Denial of Service

Reported Feburary 14, 2000 by Laurent LEVIER

VERSIONS AFFECTED
Netopia Timbukto Pro 2.0b650

DESCRIPTION

It is possible to cause a denial of service (DoS) condition on the Timbuktu Pro software by playing on an error with the authentication protocol.

To cause the DoS condition, connect and disconnect on port TCP/407 which causes TCP port 1417 to begin listening. Then connect on TCP port 1417 using a telnet client and then disconnect without performing any action. This causes the services to hang where a restart is required in order for the software to operate normally again.

VENDOR RESPONSE

Netopia is aware of the problem and is working on a fix for the matter.
