TIBCO SmartSockets RTserver Heap Overflow Vulnerability
------------------------------------------------------------------------

SUMMARY

<http://www.tibco.com/software/messaging/smartsockets/> TIBCO
SmartSockets is "a message passing framework used to transport messages
over disparate channels. The RTserver is the server component of the
framework". 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.

DETAILS

Vulnerable Systems:
* TIBCO SmartSockets version 6.8.0

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.

Analysis:
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.

Vendor response:
TIBCO has addressed this vulnerability by releasing new versions of their
software. For more information, consult their advisory at the following
