• – Vulnerability Details:
  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 TestCompatibilityRecordMode()
which allows a remote attacker to reliably corrupt controlled memory
regions. This behavior can be exploited to remotely execute arbitrary
code in the context of the user running the browser.
