The two part article series I wrote, titled “Linux on Power/Cell BE Architecture Buffer Overflow Vulnerabilities”, is available at IBM developerWorks. This article discusses buffer overflow vulnerabilities in Linux running on Power/Cell BE Architecture processor-based servers and how to exploit them. It also presents a complete set of assembly components for Linux on Power/Cell BE Architecture and their usage. Previous knowledge of buffer overflows is required. The article is available at:
