I have filled the stack with 'AAAA..' and overwritten the EIP value and set it to 'BBBB' and I got the segmentation fault as expected, what I don't understand is when debugging the ESP points directly to 'CCCC', isn't the ESP pointing to the top of the stack, and w...
Stack overflow (essentially a ‘buffer overflow’) occurs when a program tries to use more space than the size of the stack. This typically results in a program crash. Here we see how to troubleshoot the stack overflow error in Windows. How to Troubleshoot Windows Internal Stack Overflow Err...
can exploit buffer overflow vulnerabilities to damage objects, including ARG (actual parameter when the function is called), RETADDR (address of the next operation instruction in the memory), EBP (stack frame status value before the function is called), and LOCVAR (local variable in this ...
How to avoid buffer overflow vulnerabilities Programmers can mitigate the risk of buffer overflow attacks by always validating user input length. However, a good general way to avoid buffer overflow vulnerabilities is to stick to using safe functions that include buffer overflow protection (which memcpy...
A buffer overflow can be: Accidental.You try to do too much within one program, and you exceed the space the program gives you. The program may begin to behave erratically, and in some cases, it may stop working altogether. Intentional.Someone sends in data that's too large for your pro...

before performing any calculations or assignments, verify that the values involved are within the acceptable range to avoid overflow errors. are there any programming languages that are more susceptible to overflow errors? overflow errors can occur in any programming language if proper precautions are ...
Buffer overflow/underflow frequently happens when we did something wrong with the array index, no matter the array is heap or stack, no matter you are reading the memory or writing the memory. 1#To get a precise source code line number by valgrind report,2#It's better to build debug vers...
I am encountering memory leaks when using getline to read from stdin in C, despite ensuring that all the mallocs were freed, the problem persists when building a simple shell. As someone who is new to C, I am looking for advice on how to properly handle memory when using getl...
How do you recover, midstream, from a stack overflow overrun in "C"? Where you are using a character variable declared as char string[12], and you move 12 characters to where you only have space for 11 characters. How do you detect a stack overflow overrun midstream? If you do detect...
