<h2 id="1）具有导向性的模糊测试的挑战"><a href="#1）具有导向性的模糊测试的挑战" class="headerlink" title="1）具有导向性的模糊测试的挑战"></a>1）具有导向性的模糊测试的挑战</h2><p>Fuzzing是用于识别真实软件中的安全问题的最强大且经过验证的策略之一;它负责安全关键软件中迄今为止发现的绝大多数远程代码执行和权限提升漏洞。<br>不幸的是，模糊测试也不够有力。盲目的、随机的变异使得它不太可能在测试代码中达到某些代码路径，从而使一些漏洞超出了这种技术的范围。<br>已经有许多尝试来解决这个问题。早期方法之一 - 由Tavis Ormandy开创 - 是一种 <strong>语义库蒸馏（corpus distillation）</strong> 。网上找到的一些大型语料库中往往包含大量的文件，这时就需要对其精简，该方法依赖于覆盖信号从大量高质量的候选文件语料库中选择有趣种子的子集，然后通过传统方式对其进行模糊处理。该方法非常有效，但需要这样的语料库随时可用。正因为如此，<strong>代码覆盖率</strong> 也只是衡量程序执行状态的一个简单化的度量，这种方式并不适合后续引导fuzzing测试的。<br>其他更复杂的研究集中在诸如 <strong>程序流分析（“concoic execution”），符号执行或静态分析</strong> 等技术上。所有这些方法在实验环境中都非常有前景，但在实际应用中往往会遇到可靠性和性能问题 - 部分高价值的程序都有非常复杂的内部状态和执行路径，在这一方面符号执行和concolic技术往往会显得不够健壮（如路径爆炸问题），所以仍然稍逊于传统的fuzzing技术。</p>
