PEB和TEB资料整合

一、概念

　　TEB（Thread Environment Block，线程环境块）系统在此TEB中保存频繁使用的线程相关的数据。位于用户地址空间，在比 PEB 所在地址低的地方。进程中的每个线程都有自己的一个TEB。一个进程的所有TEB都以堆栈的方式，存放在从0x7FFDE000开始的线性内存中，每 4KB为一个完整的TEB，不过该内存区域是向下扩展的。在用户模式下，当前线程的TEB位于独立的4KB段，可通过CPU的FS寄存器来访问该段，一般存储在[FS:0]。在用户态下WinDbg中可用命令$thread取得TEB地址。

 　　PEB（Process Environment Block，进程环境块）存放进程信息，每个进程都有自己的PEB信息。位于用户地址空间。在Win 2000下，进程环境块的地址对于每个进程来说是固定的，在0x7FFDF000处，这是用户地址空间，所以程序能够直接访问。准确的PEB地址应从系统 的EPROCESS结构的0x1b0偏移处获得，但由于EPROCESS在系统地址空间，访问这个结构需要有ring0的权限。还可以通过TEB结构的偏 移0x30处获得PEB的位置，FS段寄存器指向当前的TEB结构：

mov eax,fs:[0x30]

mov PEB,eax

在用户态下WinDbg中可用命令$proc取得PEB地址。

二、TEB偏移
FS:[000]   指向SEH链指针
FS:[004]  线程堆栈顶部
FS:[008] 线程堆栈底部
FS:[00C]  SubSystemTib
FS:[010]  FiberData
FS:[014] ArbitraryUserPointer
FS:[018]  指向TEB自身
FS:[020] 进程PID
FS:[024] 线程ID
FS:[02C] 指向线程局部存储指针
FS:[030] PEB结构地址（进程结构）
FS:[034] 上个错误号
