TIBCO SmartSockets RTserver Multiple Untrusted Pointer Offset Vulnerabilities



TIBCO SmartSockets is a message passing framework used to transport messages over disparate channels. The RTserver is the server component of the framework. More information can be found on the vendor's web site at the following URL.


Remote exploitation of multiple untrusted pointer offset vulnerabilities in TIBCO Software Inc.'s SmartSockets RTserver may allow an attacker to crash the service or execute arbitrary code with SYSTEM privileges.

When processing requests, SmartSockets uses values from the requests as offsets added to valid pointers. The resulting pointer values are then used in various memory operations. Since attackers can control these offset values, potentially exploitable conditions arise.


Exploitation allows an attacker to execute arbitrary code with SYSTEM privileges. Unsuccessful attempts will likely crash the RTserver. The service does not restart, which makes repeated exploitation attempts more difficult.

The RTserver is the core component of the SmartSockets framework. Without it, applications will be unable to pass messages. The severity of these issues will likely vary depending on the the application using the SmartSockets framework.


iDefense has confirmed the existence of these vulnerabilities in TIBCO SmartSockets version 6.8.0. Previous versions may also be affected.


iDefense is currently unaware of any workarounds for these issues.
