The above is an example code for performing buffer overflow attack, it works when compiled using clang , but not when compiled using gcc. I think the problem is than of array alignment. On using the compile flag -mpreferred-stack-boundary=2 the program do works in gcc. Bu...
Buffer Overflow Attack – Vulnerability in Stack Most of the vulnerability based on buffer overflows aim at forcing the execution of malicious code, mainly in order to give a root shell to the user. The malicious instructions are stored in a buffer, which is overflowed to allow an unex... ...
