What causes the buffer overflow condition? Broadly speaking, buffer overflow occurs anytime the program writes more information into the buffer than the space it has allocated in the memory. This allows an attacker to overwrite data that controls the program execution path and hijack the control of the program to execute the attacker’s code instead the process code. For those who are curious to see how this works, we will now attempt to examine in more detail the mechanism of this attack and also to outline certain preventive measures. From experience we know that many have heard about these attacks, but few really understand the mechanics of them. Others have a vague idea or none at all of what an overflow buffer attack is. There also those who consider this problem to fall under a category of secret wisdom and skills available only to a narrow segment of specialists. However this is nothing except for a vulnerability problem brought about by careless programmers.
