This talk will go over all the protection mechanisms that are available to developers and package maintainers. This includes PIE, RELRO, gcc stack protector, and FORTIFY_SOURCE. It will explain what kind of attacks these prevent and how they work. More importantly, this talk will also go over limitations, short comings, and failures of these mechanisms. Some tools and techniques for analysis will be presented. The attendee will leave with a better understanding of how protected any given binary actually is.
