You are probing for buffer overfl ow vulnerabilities in a web application that makes extensive use of native code components. You fi nd a request that may contain a vulnerability in one of its parameters; however, the anomalous behavior you have observed is diffi cult to reproduce reliably. Sometimes submitting a long value causes an immediate crash. Sometimes you need to submit it several times in succession to cause a crash. And sometimes a crash occurs after a large number of benign requests. What is the most likely cause of the application’s behavior?
