Abstract: In view of the extensiveness and seriousness of the buffer overflow vulnerability, on the basis of studying the principle of buffer overflow vulnerability, attacking methods of buffer overflow vulnerability were analyzed according to local buffer overflow attack and remote buffer overflow attack, and guard strategies for two kinds of buffer overflow vulnerabilities are proposed. Experiments show that the local and remote buffer guard strategies can effectively solve the harm caused by buffer overflow vulnerabilities.

Key words: buffer overflow vulnerability, local buffer overflow, remote buffer overflow, guard strategy, Shellcode
