Isolating the root cause of a heap-based buffer overflow can be tricky at best. Thankfully, Microsoft provides a great tool called the Application verifier, which makes the process significantly gentler. In this post, we will look at how to use the Application Verifier to pinpo...
此示例演示了内存访问发生在堆分配对象的边界之外时产生的错误。 示例- 经典堆缓冲区溢出 C++ // example1.cpp// heap-buffer-overflow error#include<stdlib.h>#include<string.h>intmain(intargc,char**argv){char*x = (char*)malloc(10*sizeof(char));memset(x,0,10);intres = x[argc *10];// ...
#raw_input("sleep for a while to avoid HTTPContext buffer problem!") sleep(3) #这里 sleep 很关键,后面会解释 client_socket.send(payload) 下面我们开始考虑 payload 该如何构造,首先我们使用gdb观察程序在 buffer overflow 的时候的堆布局是怎样的,在我的机器上很不幸的是可以看到被溢出的 chunk 正好紧跟...

A method includes stalling a call to a heap allocation function originating from a request by an application for a block of heap buffer, predicting a block of the heap buffer to fulfill the request, and determining if a forward link (F-link) and a backward link (B-link) of the ...
