 Forums >>  Brainstorms - General  >>  Runtime tracking a buffer in memory to find possible buffer overflows

Topic created on: February 22, 2011 03:14 CST by GIR .

Hi,

a programm receives an income buffer via network.
Now you want to find loops within the programm that copy (parts) of the buffer onto the stack to determine wether or not the loop length is influenced by data from the buffer.
If true you modify the relevant buffer data to see if an buffer overflow occurs.

I started to c-code a prog to keep track on the buffer and every copy of the buffer in memory.
My question is: do you see any upcoming problems i might ve overseen and more important, is there already a debugger capable of solving what i m trying to do?
