ssl - 尝试使用 OpenSSL 1.0.1f 用 AFL-FUZZ 重新创建 Heatbleed

Question

我在这里尝试在 1.0.1g 之前的 openssl 版本上重现 Heartbleed 错误，因此我选择了 openssl 1.0.1f。我安装了 AFL-FUZZ，然后安装了 openssl。在this的帮助下和 this链接 我想我已经安装了 openssl 但最后它给了我一个奇怪的错误

我运行了 openssl version 命令，它运行成功，给我输出 OpenSSL 1.0.1f 6 Jan 2014 所以我认为它已经正确安装(不确定要安装什么处理错误)。

现在下一步是简单地找到一个代码来使用我找到的 openssl here握手.c 文件。但是它没有编译成功。 afl-gcc handshake.c libssl.a libcrypto.a -o handshake -I ssl/include -ldl 错误是

请建议我如何修复这些错误。

提前致谢。

编辑:

到目前为止，我所做的是以 root 权限安装 openssl。我工作但给了我很多关于手动安装的错误，即大多数错误看起来像 item= expecting something other than a integer。我手动将这些行更改为字符 =item 1 -> =item '1'。在根目录的 apps 和 ssl 文件夹发生变化后，我终于让它工作了。最终安装看起来像在 make 和 make install 之后

The program 'openssl' is currently not installed. You can install it by   typing:
apt-get install openssl

现在我认为安装没有错误，但我仍然没有安装 openssl，因为它说还没有安装这样的包。

请帮忙。

正如我在已编辑帖子中添加的那样，当我以 root 身份运行安装时，openssl 安装中的错误消失了。我使用了以下命令序列；

make clean
./config no-shared no-idea no-mdc2 no-rc5 zlib enable-tlsext
make depend
make && make install

正如上面在问题的编辑版本中所讨论的，它给了我 .pod 文件中的错误，我一个一个地解决了这些错误(想知道是否有人有更聪明的方法)。

编译后，现在错误仍然在编辑部分，在将 openssl 安装路径添加到 $PATH 环境变量后立即解决。我在 .basrc 和 .profile 文件中添加了以下行。

export PATH="$PATH:/usr/local/ssl/bin" 

现在 openssl 工作正常。

然而，使用 openssl 编译 handshake.c 是用这个命令进行的

AFL_USE_ASAN=1 afl-gcc handshake.c -lcrypto -lz libssl.a  -o handshake -ldl

最后

afl-fuzz -i testcases -o findings -m none -- ./handshake

希望这对 future 的 google 员工有帮助。

谢谢。
