Justin Engler and Tyler Lukasiewicz introduce WebAssembly semantics and examine the security risks and potential native exploits in the browser.

The goal of this talk is to provide a basic introduction to WebAssembly and examine the actual security risks that a developer may take on by using it. We will cover the low-level semantics of WebAssembly, including the Javascript API, the linear memory model, and the use of tables as function pointers.
