摘　　要：当前有关格式串漏洞的检测技术大多局限于源代码层次,针对二进制文件的研究较少。以格式串栈指针和参数栈指针为切入点,分析研究了格式串漏洞的攻击原理,在目标代码的层次提出了一种新的格式串漏洞检测技术,给出了构造攻击代码的具体方法,重点研究了不同系统中攻击代码的构建过程,最后结合实例对检测方法进行了验证。通过与实例源代码的比较,充分证明了检测方法的有效性,具有重要的应用价值。Current detection techniques are mostly limited to the source code level, and research on the binary files is few. Based on the stack pointer and the argument pointer of the format-string, the attacking principles of format-string vulnerabilities were researched. A new method to detect format-string vulnerabilities in binary files was brought forward. By analyzing the method that the model adopted, the particular means and processes to construct the attacking codes were presented. In order to improve the effectiveness of the detection, the attacking code constructions for different systems were studied. At last, an example was given to demonstrate the validity of the detection model.
