Research on Key Data Structure Localization Technology of Buffer Overflow Vulnerability

Buffer overflow vulnerability is one of the most common and harmful vulnerabilities in computer software. This paper analyzed and summarized the general method and process of testing buffer overflow vulnerability in software. And the key data structure localization technology in software buffer overflow vulnerability was also studied in this paper. By constructing special filling data and designing location algorithm, this paper presented a new localization technology based on block localization. The technology can locate key data structure address of buffer overflow vulnerability fleetly and exactly. It can effectively assist testing buffer overflow vulnerabilities in software security.
