Qt的插件机制

<br />Qt有两种与插件有关的API。一种用来扩展Qt本身的功能,如自定义数据库驱动,图像格式,文本编解码,自定义分格,等等,称为Higher-Level API。另一种用于应用程序的功能扩展,称为Lower-Level API。前一种是建立在后一种的基础之上的。这里讨论的是后一种,即用来扩展应用程序的Lower-level API。<br /><br /><br />让应用程序支持插件扩展的步骤:<br />  1. 定义一个接口集(只有纯虚函数的类),用来与插件交流。<br />  2.

揭开Shellcode的神秘面纱

对于初期接触网络安全的人来说,Shellcode是很神秘的东西,对于网络攻击过程中的嗅探信息、漏洞剖析都是可以理解的,但真正利用漏洞入侵时,通过把一段二进制码送入后并执行,就可以获得目标机器的控制权,之后的事情是属于爱好者学习技术,还是黑客的行为,就看攻击者的一念之差了。Shellcode就好象神秘的武器,安全防护变得如此不堪一击。Shellcode究竟是什么样的程序?是什么特殊代码?如何才能学会编写?我下面收集了几类常见的Shellcode,主要是学习使用。它其实也是一般的软件程序,主要是因为二进制码的“

Linux下缓冲区溢出攻击的原理及对策

<br />前言<br />从逻辑上讲进程的堆栈是由多个堆栈帧构成的,其中每个堆栈帧都对应一个函数调用。当函数调用发生时,新的堆栈帧被压入堆栈;当函数返回时,相应的堆栈帧从堆栈中弹出。尽管堆栈帧结构的引入为在高级语言中实现函数或过程这样的概念提供了直接的硬件支持,但是由于将函数返回地址这样的重要数据保存在程序员可见的堆栈中,因此也给系统安全带来了极大的隐患。<br />历史上最著名的缓冲区溢出攻击可能要算是1988年11月2日的Morris Worm所携带的攻击代码了。这个因特网蠕虫利用了fin
