基于源代码的缓冲区溢出预防技术

基于缓冲区溢出的攻击是一种常见的安全攻击手段,也是目前惟一最重要最常见的安全威胁。在所有的软件安全漏洞中,缓冲区溢出漏洞大约占一半。该文从编程的角度分析了缓冲区溢出攻击,并提出在源代码阶段尽量避免缓冲区溢出的方法。

Prevention Technology Based on Buffer Overflow of Source Code

The attack,based on the buffer overflow,is a common means of security attacks and is the only most common security threats at present.Buffer overflow vulnerabilities account for about half Of all the software vulnerabilities.In this paper,from programming point of view,the buffer overflow attacks are analyzed and the methods of avoiding buffer overflow at the stage of source code are introduced.
