Security and Correctness in Wasmtime - Nick Fitzgerald, Bytecode Alliance
WebAssembly programs are sandboxed and isolated from one another and from the host, so they can’t read or write external regions of memory, transfer control to arbitrary code in the process, or freely access the network and filesystem. This makes it safe to run untrusted WebAssembly programs: they cannot escape the sandbox to steal private data from elsewhere on your laptop or run a botnet on your servers. But these security properties only hold true if the WebAssembly runtime’s implementation is correct. This talk will explore the ways we are ensuring correctness in the Wasmtime WebAssembly runtime and in its compiler, Cranelift.
