WebSymbolic execution. The key idea behind this technique is to execute a program over symbolic, rather than concrete, inputs. Each symbolic input can, for instance, represent … WebSymbolic execution is the process of exploring the state paths of a program given different inputs to arrive at a mathematical expression that describes the system. …
WebFuzzing is a technique of finding bugs by executing a software recurrently with a large number of abnormal inputs. Most of the existing fuzzers consider all parts of a software equally, and pay too much attention on how to improve the code coverage. It is inefficient as the vulnerable code only takes a tiny fraction of the entire code. Webin software: namely, coverage-guided fuzzing [1–3] and concolic execution [4, 5]. Fuzzing can quickly explore the input space at nearly native speed, but it is only good Figure 1: …
WebJul 10, 2024 · In this paper, we propose an algorithm, Deferred Concretization, that uses a new category for values within symbolic execution (referred to as the symcrete values) to pend concretization till they are actually needed. Our tool, COLOSSUS, built around these ideas, was able to gain an average coverage improvement of 66.94% and reduce … WebSymbolic Fuzzing¶ One of the problems with traditional methods of fuzzing is that they fail to exercise all the possible behaviors that a system can have, especially when the input …
