iDefense Security Advisory 01.15.08: TIBCO SmartSockets RTServer Multiple Untrusted Pointer Vulnerabilities

iDefense Security Advisory 01.15.08 
Jan 15, 2008


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 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
pointers. These pointer values are then used in various memory
operations. Since attackers can control these 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.


TIBCO has addressed these vulnerabilities by releasing new versions of
their software. For more information, consult their advisory at the
following URL. 


The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CVE-2007-5655 to this issue. This is a candidate for inclusion in
the CVE list (, which standardizes names for 
security problems.
