This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of IBM Rational Rhapsody. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page or open a malicious file.

pointers may be passed as arguments to InsertMarker() which in turn can
allow an attacker to corrupt memory in a controlled fashion. This
behavior can be exploited to remotely execute arbitrary code in the
context of the user running the browser.
