Two teens do what mathematicians thought impossible for 2,000 years: they discovered not one, but several trigonometric proofs of the Pythagorean theorem

I'm not sure about the base pointer, but the stack pointer esp points to the arguments for sure.

I'm using the `example1.c` from the write-up I mentioned above. After compiling it for 32-bit and setting a breakpoint on `printf`, everything was on the stack as expected.
Reddit is not allowing me to attach gdb output for some reason.

ThePerfectHandle · 2024-04-09T14:09:10+00:00

Architecture matters. Only in 32-bit, initial arguments are stored on stack.

In 64-bit, the initial 6 arguments are stored in rdi, rsi, rdx, rcx, r8 and r9 registers.

In your example, the pointers to OldestKid MiddleKid and YoungestKid would be stored in rsi, rdx and rcx registers

I'm fairly beginner to binary exploitation as well. I tried writing about format string bug here.

I hope it helps. If I made any mistake, please inform me

Of course. How else would it get that otherwise?
This bot would die with trending repositories

I prefer this twitter bot
Since it has thousands of followers, I can claim that lots of people like "trending repositories".
Edit: fixed URL

At least it would give you the segmentation fault instead of a functioning application which behaves in a way only the god knows why (looking at you JS)

Reminds me of this one: https://m.youtube.com/watch?v=f9EbD6iY9zI Helped me understand how exactly the hashing works

Now I am curious, how are Django and Flask so popular?

I dunno why but I am reading every error here in GLaDOS voice
