PE标头要求

Question

PE文件（PE / COFF）的要求是什么？应该设置哪些字段，哪个值最小，以使其能够在Windows上“运行”（即执行“ret”指令然后关闭，没有错误）。

我首先建立的库是链接器：现在，我遇到的问题是PE文件（PE / COFF）。 我不知道PE文件在我的平台上实际执行之前需要什么。我的测试平台是Vista。我收到一条错误消息，说“这不是一个有效的Win32可执行文件。”当我通过双击执行它时，我得到一个“拒绝访问”。使用CLI cmd 执行时。我有两个部分，.text和.data。

我已经实现了几个在线文档提供的PE头文件，即MSDN和其他一些第三方文档。如果我使用十六进制编辑器，它看起来几乎像一个普通的PE文件。我不使用任何导入，也不使用IAT，也不使用PE头中的任何目录。

编辑：我添加了一个导入表，仍然不是一个有效的.exe文件，我的Windows说。我试过使用最小的PE文件指南中提到的值。没运气。真正唯一我无法弄清楚的是需要什么，什么不需要。一些指南告诉我一切都是必需的，而其他人则说关于掠夺：它可以是零。

我希望这是足够的信息。 提前谢谢。

Answer 1

将粘贴复制到十六进制编辑器是一件非常痛苦的事情，所以不幸的是，我不能说任何太聪明的东西。

PE文件中需要注意的事项： 确保您的DOS标头有效。 确保IMAGE_OPTIONAL_HEADER格式正确，因为尽管名称不同，Windows并不喜欢它没有正确完成。

有关MS格式之上和之外的更多信息，请查找pe.txt，这是我所知道的PE格式的最佳自制指南之一。

如果您只发布字节，我可以尝试将它放在我自己的PE解析器中，看看我是否可以提供更多帮助。

这个article about creating tiny PE executables可能会引起人们的兴趣：特别是，它提到Win2k加载器需要导入KERNEL32.DLL，所以这可能值得研究。

Answer 3

您尝试执行的操作取决于您使用的Windows版本。例如，在Windows 2000上读取PE文件的方式与Windows 7读取它们的方式不同。我是OSX用户，但在Windows 7上，我无法以在Windows 2000及更早版本上运行的方式操作PE文件。我没有测试过XP或Vista（或2000和Win7之间的其他版本），看看Windows何时开始以不同的方式阅读PE。在Windows 7上，MS-DOS标头和存根中的每一位内存都被忽略。唯一重要的两个部分是“幻数”（一个等于“MZ”的WORD）和PE Offset，它是一个DWORD，用于定义PE头的内存位置。我不确定Windows是否真正忽略了MS-DOS标头中的所有其他值和100％的时间存根，但不包括我刚才提到的两个，如果所有其他值都设置为0，则有效的可执行程序将正常运行

在Windows 2000及更早版本中，我不知道上面提到的是否属实，但是当时允许修改MS-DOS存根的长度（或者可能删除它），前提是PE偏移值仍然指向内存中找到PE头的正确位置。在Windows 7上，如果你完全修改MS-DOS存根的长度，即使PE Offset指向正确的修改位置，Windows也不会运行exe并声称它不是有效的Win32应用程序。

这是PE文件的MS-DOS部分在Windows 7上可以拥有的最少，同时仍然具有有效的，可正常运行的可执行文件。这一点不能缩短。

希望这能解决一些问题。

你可以试试像.NET 2.0 IL Assembler这样的书。本书有一整章专门讨论PE格式可执行文件的外观（以及.Net PE的外观）。

您还可以尝试使用PE文件读取器加载PE文件并检查结果。 如果PE阅读器与你的PE挣扎，那么你有一个指向失败的指针。

这是我写的PE File Reading DLL（带来源）。还有一个使用它的GUI（带源）。

源是完全开源的（不受GPL阻碍）所以你可以用它做你想做的事情（除了在它上面施加GPL，这会阻止它完全打开），包括关闭你的版本。 / p>

Microsoft PE / COFF规范是我所知道的唯一规范。
