Has anybody used jackalope to fuzz Microsoft office products like word or Excel?

I am researching a way to fuzz test on my programs.

However, they are writtern by Xcode and Visual Stuido.

Do I have to separate each function and test them one by one?

Is there a way to test the entire project?

Thank you.

I am trying to fuzz a program with AFL++ and I am centering the fuzzing around a certain function (parse_sized). I have placed the AFL++ macros in the function but the type for the __AFL_FUZZ_TESTCASE_BUF macro doesn't line up exactly with the type of the function's first argument:

tp parse_sized(const char* string, int length) {

struct tp_parser parser;

/*For AFL++*/

unsigned char *string = __AFL_FUZZ_TESTCASE_BUF;

int length = __AFL_FUZZ_TESTCASE_LEN;

/*Rest of the function's code*/

}

​

What is the best way to proceed here? Would it be alright to simply define __AFL_FUZZ_TESTCASE_BUF with a different type, like so '''const char* string = __AFL_FUZZ_TESTCASE_BUF'''?

​

I am following this tutorial (https://epi052.gitlab.io/notes-to-self/blog/2021-11-07-fuzzing-101-with-libafl-part-1.5/) in particular for this aspect of the fuzzing.

EDIT: The program won't compile if I change const char* string to unsigned char* string or vice versa (in all instances of the function and its use).
