TIBCO SmartSockets RTserver Heap Overflow Vulnerability



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 a heap overflow vulnerability in TIBCO Software Inc.'s SmartSockets RTserver may allow an attacker to crash the service or execute arbitrary code with SYSTEM privileges.

A heap overflow vulnerability exists within the code responsible for processing requests. Two distinct values from the request are used for the allocation size and the amount of data copied. Since both values are attacker controlled, this can lead to a heap overflow, potentially resulting in the execution of arbitrary code.


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.
