Buffer Overflow Attack

Exploits, vulnerabilities, and buffer-overflow techniques have been used by malicious hackers and virus writers for a long time. In order to attack and get the remote root privilege, using buffer overflow and suidprogram has become the commonly used method for hackers. This paper include vast idea and information regarding the buffer overflow as history of Vulnerabilities, buffers, stack, registers, Buffer Overflow Vulnerabilities and Attacks, current buffer over flow, Shell code, Buffer Overflow Issues, the Source of the Problem, prevention/detection of Buffer Overflow attacks and Finally how to react towards Buffer Overflows. The objective of this study is to take one inside the buffer overflow attack and bridge the gap between the descriptive account and the technically intensive account
