| summary: Buffer overflow in WASM modules in misc/wasm and cmd/link |
| description: |- |
| When invoking functions from WASM modules, built using GOARCH=wasm GOOS=js, |
| passing very large arguments can cause portions of the module to be overwritten |
| with data from the arguments due to a buffer overflow error. |
| |
| If using wasm_exec.js to execute WASM modules, users will need to replace their |
| copy (as described in https://golang.org/wiki/WebAssembly#getting-started) after |
| rebuilding any modules. |
