AFL相关详见AFL安全漏洞挖掘

GCOV相关详见GCOV覆盖率分析

现将两者结合，即进行fuzz模糊测试，又进行GCOV覆盖率分析。

一、代码示例

二、afl-cov工具下载

GitHub - mrash/afl-cov: Produce code coverage results with gcov from afl-fuzz test cases

三、编译带覆盖率的版本并启动afl-cov

cd vulnerable_cov/
gcc -fprofile-arcs -ftest-coverage -o vulnerable vulnerable.c
~/afl-cov-master/afl-cov -d ../vulnerable/outputs --live --coverage-cmd "cat AFL_FILE | ./vulnerable" --code-dir . --enable-branch-coverage

命令详解请参考：GitHub - mrash/afl-cov: Produce code coverage results with gcov from afl-fuzz test cases

中的README.md

AFL%E7%BC%96%E8%AF%91%E6%8F%92%E6%A1%A9%E5%B9%B6%E8%BF%90%E8%A1%8Cafl-fuzz">四、AFL编译插桩并运行afl-fuzz

cd vulnerable
afl-gcc -o vulnerable vulnerable.c
afl-fuzz -i testcases/ -o outputs ./vulnerable

五、结果查看

afl-fuzz运行过程中，afl-cov会收集结果，待"ctrl+c"退出afl-fuzz，最终覆盖率网页结果会出现。
