TIBCO SmartSockets Product Family (RTworks) vulnerability

   Original release date: April 28 2009
   Last revised: --
   Source: TIBCO Software Inc.


Systems Affected

   TIBCO SmartSockets Product Family (RTworks) versions below 4.0.5

   The following components are affected:

     * TIBCO RTworks Server (rtserver)
     * TIBCO RTworks libraries (rtipc, rtutil)


Overview

   TIBCO RTworks components listed above contain buffer overflow
   vulnerabilities in the processing of inbound data.  The impact of
   these vulnerabilities may include remote execution of arbitrary code,
   information disclosure, and denial of service.


I. Description

   TIBCO has released updates which address critical vulnerabilities in
   the server and library components of TIBCO RTworks.

   These vulnerabilities directly affect the RTworks server (rtserver)
   and applications utilizing the RTworks libraries.

   TIBCO strongly recommends sites running the affected components to
   install the update or take mitigating action as appropriate.


II. Impact

   The impact of these vulnerabilities varies depending on the operating
   system and the privilege levels of the user that invokes the server or
   application.

   The successful exploit will allow arbitrary code execution with the
   privileges of the user that invoked the server or application.


III. Solution

   Upgrade TIBCO RTworks to version 4.0.5 or above.  This is
   strongly recommended.

   If an upgrade is not possible, the following actions can mitigate
   the vulnerabilities:

     * Disable the rtserver UDP port using the rtserver configuration
       file.
     * Utilize a firewall to restrict access to the rtserver.
     * Use a user with restricted privileges to invoke the rtserver
       or application.
     * Invoke the server or application from a chroot environment.
       This will restrict the ability to access or modify information
       in the event of a successful exploit.
