本文记录csapp实验题中attack bomb的分析过程;该实验要求利用程序的缓冲区溢出漏洞,通过给予特定输入内容,改变程序正常的运行逻辑,实现对程序的攻击操作;通过这个攻击过程可以加强对栈区数据机制的理解, 并对缓冲区溢出攻击有更直观的认识,日常写代码时也会从此格外注意。实验给了两个待攻击的目标程序,ctarget和rtarget,...
Improved buffer overflow protection for a computer function call stack is provided by placing a predetermined ShadowKEY value on a function's call stack frame and copying the ShadowKEY, a caller EBP, and a return pointer are pushed onto a duplicate stack. The prologue of the function may be ...
最近做了一个buffer overflow的mini-project,用ssh登陆一个本地的virtualBox运行的Linux,利用buffer overflow获取root权限。详细过程请观看视频。 参考论文 - Smashing The Stack For Fun And Profit 内存layout: 黑客入门 - 堆栈溢出攻击 (buffer overflow attack)...[...
防止Stack smash attack或buffer overflow的方法: (1)、部署 Canary 漏洞缓解措施 GCC编译器默认开启该机制,可加-fno-stack-protector关闭该机制 原理: 其实就是在ebp之前(aarch64应该叫FP之前)加入一个canary值,如果发生了Stack smash attack对return addr的攻击,那么canary的值势必也会被修改。所以在程序返回时通过...
The flaw was an instance of a buffer overflow, a security vulnerability that has been discussed for 40 years yet remains one of the most frequently reported types of remote attack against computer systems. In 2004, the national cyber-security vulnerability database (nvd.nist.gov) reported 323 ...
