SeedLab 2016 版本 Buffer-Overflow Vulnerability Lab 把数据写在固定长度的缓冲区的外面, 但是程序在向缓冲区内写入数据时没有得到良好的保护, 自己程序的栈结构就会被缓冲区外的数据破坏, 这些数据中如果有 "不法分子" 就会进一步制造破坏. 这个实验只需要一台虚拟机, 电脑舒服一些. 实验指导 https://seedse...

2 Buffer Vulnerability Lab The first part is the Buffer Vulnerability Lab (http://www.cis.syr.edu/~wedu/seed/Labs_ 16.04/Software/Buffer_Overflow/). You are required to do it in C, not in Python, though the lab instructions include directions for both. This is very similar to what I ...

在seedlab的缓冲区溢出实验中,我们通过编写代码来模拟缓冲区溢出攻击。以下是实验步骤的详细描述:1. 安装和配置Python环境,确保安装了`socket`库。2. 使用`socket`库创建一个TCP套接字。3. 使用`send()`方法向服务器发送数据,并设置超时时间。4. 接收服务器返回的数据,
