Proj THUDBFuzz Paper Reading: Sequence Directed Hybrid Fuzzing

Abstract

技术: sequence directed + concolic execution
工具: Berry
实验:
比较对象: BugRedux, AFLGo, LOLLY, QSYM
效果:

  1. outperforms
  2. 找到7个CVEs

Intro

  1. enhance the target seq with statements which must be explored before the necessary nodes
  • 用在到达目标序列之前一定需要到达的前置(条件)语句来拓展target sequences
  1. a new seed energy scheduling algo + test case priority management
  2. 比较种子的执行路径之后,定义最后一个匹配的statement/node为switch point,在这个点尝试符号执行

Motivation

Design
