Using buffer overflow to execute shell code

Using buffer overflow to execute shell code

wish of those help Well, I think maybe this is a like a Buffer Overflow Lab in Computer Systems: A Programmer's Perspective. First, use objdump to get the static address. Second, run it with gdb to find out the address of the stack. Then, fill the buffer with such a string that overwrites the return address to the buffer (so that you can put exploit code, alternatively, you could invoke other code in the program).
Check out this pdf which serves as a guide to this lab. It could provide you with some insights.
If the stack is 'flipped' can you still execute shell code using a buffer overflow?

wish of those help Short answer: yes.
Function A allocates buffer on the stack for variable Q. A calls B passing address of Q as a parameter. B overflows the buffer nuking the return address back to A.

This might help you it looks like paramsVBO is the bound buffer when that else statement is called and there is no call to bufferData to initialize that buffer target with any information
see this link for info on creating buffers. other than that it looks like you're on the right track, just that buffer isn't being initialized (at surface glance anyway)

like below fixes the issue A simple way to generate such a code would be to write the desired functionality in C. Then compile it (not link) using say gcc as your compiler as
code :
gcc -c shellcode.c
odjdump -D shellcode.o

I hope this helps . That’s an old article, but I’ve cited it too. The problem is that your code is “identical to the reading.” Those aren’t magic numbers from a script. Pay close attention to how Aleph One determined which values to smash the stack with for that program.
And keep in mind that the article is from 1996, and the kernel and GCC devs have read it too.
