Prevent Wasm Compiler Bugs Early | Fastly

iximeow, Chris Fallin

We recently discovered a compiler bug in part of the WebAssembly compiler that we use for Compute@Edge, that could have allowed a WebAssembly module to access memory outside of its sandboxed heap. But because of the people, processes, and tools we have in place, the bug was caught and patched on our infrastructure before it was exploited.
