缓冲区溢出漏洞分析技术研究进展

摘要

First,in this paper,the breadth and risk of buffer overflow vulnerabilities are introduced.Then,from the aspect of how to exploit a buffer overflow vulnerability,an overview is provided on the definition of buffer overflow vulnerabilities,memory organization in operation systems,and classification of buffer overflow attacks.Based on the research,buffer overflow analysis technologies are classified into three categories:automatic detection,automatic repair,and run-time protection.Each types of technologies are introduced,analyzed and discussed according to the classification.Finally,three possible research directions in the field of buffer overflow vulnerability analysis are discussed:(1) analyzing binary code;(2) using machine learning algorithms;(3) combining multiple technologies for analysis.%首先介绍了缓冲区溢出漏洞危害的严重性和广泛性,然后,从如何利用缓冲区溢出漏洞的角度,依次介绍了缓冲区溢出漏洞的定义、操作系统内存组织方式以及缓冲区溢出攻击方式.将缓冲区溢出分析技术分为3类:自动检测、自动修复以及运行时防护,并对每一类技术进行了介绍、分析和讨论.最后,对相关工作进行了总结,并讨论了缓冲区溢出分析领域未来可能的3个研究方向:(1)对二进制代码进行分析;(2)结合机器学习算法进行分析;(3)综合利用多种技术进行分析.
