一句话:提出 DeFault,旨在实现大规模崩溃场景下快速、忠实且高效的分诊。
现代模糊测试基础设施在漏洞发现上取得显著成功,随之产生数量空前的崩溃样本。为定位根因,对大量崩溃进行快速且忠实的崩溃分诊(crash triage)一直是重要目标。然而,实际中很难在降低分析不精确性的同时不牺牲效率,因此该目标尚未实现。论文 DeFault 聚焦这一精度与效率的权衡,围绕大规模崩溃分诊展开。摘要仅给出问题背景与动机,未披露具体方法、系统设计与实验评估;从标题推断,DeFault 应是面向崩溃分诊的系统或技术。
With the considerable success achieved by modern fuzzing infrastructures, more crashes are produced than ever before. To dig out the root cause, rapid and faithful crash triage for large numbers of crashes has always been attractive. However, hindered by the practical difficulty of reducing analysis imprecision without compromising efficiency, this goal has not been accomplished.
