PE目录的名称

Question

我正在研究一种PE解剖器,并且遇到了一些非常不寻常的事情.PE格式中目录的名称和顺序似乎根据您的外观而有所不同:

从PEReader(perdr):

#define IMAGE_DIRECTORY_ENTRY_EXPORT          0   // Export Directory
#define IMAGE_DIRECTORY_ENTRY_IMPORT          1   // Import Directory
#define IMAGE_DIRECTORY_ENTRY_RESOURCE        2   // Resource Directory
#define IMAGE_DIRECTORY_ENTRY_EXCEPTION       3   // Exception Directory
#define IMAGE_DIRECTORY_ENTRY_SECURITY        4   // Security Directory
#define IMAGE_DIRECTORY_ENTRY_BASERELOC       5   // Base Relocation Table
#define IMAGE_DIRECTORY_ENTRY_DEBUG           6   // Debug Directory
#define IMAGE_DIRECTORY_ENTRY_ARCHITECTURE    7   // Architecture Specific Data
#define IMAGE_DIRECTORY_ENTRY_GLOBALPTR       8   // RVA of GP
#define IMAGE_DIRECTORY_ENTRY_TLS             9   // TLS Directory
#define IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG    10   // Load Configuration Directory
#define IMAGE_DIRECTORY_ENTRY_BOUND_IMPORT   11   // Bound Import Directory in headers
#define IMAGE_DIRECTORY_ENTRY_IAT            12   // Import Address Table
#define IMAGE_DIRECTORY_ENTRY_DELAY_IMPORT   13   // Delay Load Import Descriptors
#define IMAGE_DIRECTORY_ENTRY_COM_DESCRIPTOR 14   // COM Runtime descriptor

在PEInfo中(更正为0-base):

0   Export
1   Import
2   Resource
3   Exception
4   Security
5   Base Reloc
6   Debug
7   Copyright
8   Global Ptr
9   TLS
10  Load Config
11  Bound Import
12  IAT
13  COM
14  Delay Import
15  (reserved)

在CFF资源管理器中:

0   Export
1   Import
2   Resource
3   Exception
4   Security
5   Relocation
6   Debug
7   Architecture
8   (reserved)
9   TLS
10  Configuration
11  Bound Import
12  IAT
13  Delay Import
14  .NET MetaData

从WINE的winnt.h:

#define IMAGE_DIRECTORY_ENTRY_EXPORT            0
#define IMAGE_DIRECTORY_ENTRY_IMPORT            1
#define IMAGE_DIRECTORY_ENTRY_RESOURCE          2
#define IMAGE_DIRECTORY_ENTRY_EXCEPTION         3
#define IMAGE_DIRECTORY_ENTRY_SECURITY          4
#define IMAGE_DIRECTORY_ENTRY_BASERELOC         5
#define IMAGE_DIRECTORY_ENTRY_DEBUG             6
#define IMAGE_DIRECTORY_ENTRY_COPYRIGHT         7
#define IMAGE_DIRECTORY_ENTRY_GLOBALPTR         8   /* (MIPS GP) */
#define IMAGE_DIRECTORY_ENTRY_TLS               9
#define IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG       10
#define IMAGE_DIRECTORY_ENTRY_BOUND_IMPORT      11
#define IMAGE_DIRECTORY_ENTRY_IAT               12  /* Import Address Table */
#define IMAGE_DIRECTORY_ENTRY_DELAY_IMPORT      13
#define IMAGE_DIRECTORY_ENTRY_COM_DESCRIPTOR    14

这里他们是一张桌子:

+------+-------------------+-------------------+-------------------+-------------------+

+------+-------------------+-------------------+-------------------+-------------------+

这些编号和顺序似乎不匹配.在PEReader和winnt.h中,条目14是COM描述符,但在CFF资源管理器中,它显示为.NET MetaData.COM和延迟导入条目似乎也可以切换.

看起来很奇怪,其中一些工具会出错.哪一个是正确的？我错过了一个新的定义吗？

您不必使用任何未记录的内容.Windows SDK附带的WinNT.h文件中找到了正确的文件(安装后,在我的机器上,它位于C:\ Program Files(x86)\ Microsoft SDKs\Windows\v7.0A\Include):

// Directory Entries

#define IMAGE_DIRECTORY_ENTRY_EXPORT          0   // Export Directory
#define IMAGE_DIRECTORY_ENTRY_IMPORT          1   // Import Directory
#define IMAGE_DIRECTORY_ENTRY_RESOURCE        2   // Resource Directory
#define IMAGE_DIRECTORY_ENTRY_EXCEPTION       3   // Exception Directory
#define IMAGE_DIRECTORY_ENTRY_SECURITY        4   // Security Directory
#define IMAGE_DIRECTORY_ENTRY_BASERELOC       5   // Base Relocation Table
#define IMAGE_DIRECTORY_ENTRY_DEBUG           6   // Debug Directory
//      IMAGE_DIRECTORY_ENTRY_COPYRIGHT       7   // (X86 usage)
#define IMAGE_DIRECTORY_ENTRY_ARCHITECTURE    7   // Architecture Specific Data
#define IMAGE_DIRECTORY_ENTRY_GLOBALPTR       8   // RVA of GP
#define IMAGE_DIRECTORY_ENTRY_TLS             9   // TLS Directory
#define IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG    10   // Load Configuration Directory
#define IMAGE_DIRECTORY_ENTRY_BOUND_IMPORT   11   // Bound Import Directory in headers
#define IMAGE_DIRECTORY_ENTRY_IAT            12   // Import Address Table
#define IMAGE_DIRECTORY_ENTRY_DELAY_IMPORT   13   // Delay Load Import Descriptors
#define IMAGE_DIRECTORY_ENTRY_COM_DESCRIPTOR 14   // COM Runtime descriptor

WINE和PEReader定义只是(正确地说我相信)从这个.h文件中借用.

这里还提到:ImageDirectoryEntryToDataEx函数
