Description Jeff Kowalczyk 2021-10-08 01:27:11 UTC

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.

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.

This is issue go#48797 and CVE-2021-38297. Thanks to Ben Lubar for reporting this issue.
