To perform the buffer overflow, we will use GDB with GEF (GDB Enhanced Features). You can find the GEF repository at: https://github.com/hugsy/gef To run the binary with GDB, use the command: gdb ./secret To determine the offset (how many A's you need to input to reach and overw...
CSAPP LAB: Buffer Overflow 这是CSAPP官网上的著名实验,通过注入汇编代码实现堆栈溢出攻击。 实验材料可到我的github仓库https://github.com/Cheukyin/CSAPP-LAB/选择buffer-overflow分支下载 linux默认开启ASLR,每次加载程序,变量地址都会不一样,所以若要关闭ASLR: sysctl -w kernel.randomize_va_space=0(赋值为2,...
诡异的是本次出现的单元测试模块是很久未动的一个模块,而且在本地的单元测试过程中,是能够运行通过的,但是在github的ci上面出问题了。 首先,报这个错误的原因肯定是我们的程序有问题,但是以前结合调试模式+sanitize功能基本能够把问题排除了,结合了github的ci出现问题,初步判断是由于GCC版本升级后,对于栈溢出的...
