TIBCO Security Advisory: April 28, 2009 - TIBCO SmartSockets®
TIBCO SmartSockets 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.
TIBCO has released updates which address critical vulnerabilities in the server and library components of TIBCO SmartSockets.
These vulnerabilities directly affect the SmartSockets server (rtserver) and applications utilizing the SmartSockets libraries.
TIBCO strongly recommends sites running the affected components to install the update or take mitigating action as appropriate.
- TIBCO SmartSockets versions below 6.8.2
The following components are affected:
- TIBCO SmartSockets Server (rtserver)
- TIBCO SmartSockets client libraries (rtconn, rtedm, rtipc, rtipcl, rtmsg, rtsm, rtutil)
The impact of these vulnerabilities varies depending on the operating system and the privilege levels of the user that invokes the server or application.
On Unix based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application.
On Windows based systems, the successful exploit will allow arbitrary code execution with the privileges of the user that invoked the server or application. If the server or application is installed as a system service, this will result in access to system privileges.
- Upgrade TIBCO SmartSockets to version 6.8.2 or above. This is strongly recommended.
If an upgrade is not possible, the following actions can mitigate the vulnerabilities:
- Disable the rtserver UDP port if it has been enabled in 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.On Unix systems, 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.
