A Denial of Service (DoS) condition exists in the Oracle 9i and 8i Server Transparent Network Substrate (TNS) Listener service. An attacker who connects to the Oracle TNS Listener (usually on port 1521) and issues the command "(CONNECT_DATA=(COMMAND=SERVICE_CURLOAD))" can cause the TNS Listener service to stop responding after the attacker closes the connection.
