尝试使用OpenSSL 1.0.1f使用AFL-FUZZ重新创建热出血
尝试使用OpenSSL 1.0.1f使用AFL-FUZZ重新创建热出血
提问于 2018-12-21 13:57:14
我在这里尝试在1.0.1g之前的openssl版本上重现Heartbleed bug，所以我选择了openssl 1.0.1f。我安装了AFL-FUZZ，然后安装了openssl。在this和this链接的帮助下，我想我已经安装了openssl，但最后它给了我一个奇怪的错误

make[2]: *** [link_app.] Error 1我运行了openssl version命令，它成功地运行并给出了输出OpenSSL 1.0.1f 6 Jan 2014，所以我认为它已经正确安装了(不确定如何处理错误)。
现在，下一步是简单地找到一个使用openssl的代码，我找到了here handshake.c文件。但是，它没有成功编译。afl-gcc handshake.c libssl.a libcrypto.a -o handshake -I ssl/include -ldl，则错误为

提前谢谢。
编辑：
因此，到目前为止，我所做的是使用root权限安装openssl。我工作，但给我太多的错误，手动安装，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'。在更改了应用程序和根目录下的ssl文件夹后，我终于让它工作了。在make和make install之后，最后的安装看起来像是
installing openssl
installing CA.sh
installing CA.pl
installing tsget
make[1]: Leaving directory `/openssl-1.0.1f/apps'
making install in test...
make[1]: Entering directory `/openssl-1.0.1f/test'
make[1]: Nothing to be done for `install'.

installing libcrypto.a
installing libssl.a
cp libcrypto.pc /usr/local/ssl/lib/pkgconfig
chmod 644 /usr/local/ssl/lib/pkgconfig/libcrypto.pc
cp libssl.pc /usr/local/ssl/lib/pkgconfig
chmod 644 /usr/local/ssl/lib/pkgconfig/libssl.pc
cp openssl.pc /usr/local/ssl/lib/pkgconfig
chmod 644 /usr/local/ssl/lib/pkgconfig/openssl.pc
root@ubuntu:/openssl-1.0.1f# openssl
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，但是我仍然没有安装openssl，因为它说还没有安装这样的包。
请帮帮忙。

正如我在编辑的帖子中添加的那样，当我以根用户身份运行安装时，openssl安装中的错误就消失了。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正如上面在编辑版本的问题中所讨论的，它给了我.pod文件中的错误，我一个接一个地解决了(我想知道是否有人有更聪明的方法)。
编译后，现在错误仍然是编辑的部分，在添加openssl安装路径到$PATH环境变量后立即解决。我在.basrc和.profile文件中添加了下面这行代码。
export PATH="$PATH:/usr/local/ssl/bin" 现在，openssl运行得很好。
但是，使用openssl编译handshake.c时会使用此命令
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希望这能对未来的谷歌人有所帮助。
谢谢。
