Preface: Every time I start learning CVE. It helps me enrich my knowledge.  Even though it was released months ago.

Background: V8 is a JavaScript and WebAssembly engine developed by Google for its Chrome browser. Each WebAssembly module executes within a sandboxed environment separated from the host runtime using fault isolation techniques.

Ref: wasmtime is a runtime for WebAssembly. The 19.0.0 release of Wasmtime contains a regression introduced during its development which can lead to a guest WebAssembly module causing a panic in the host runtime. A valid WebAssembly module, when executed at runtime, may cause this panic. This vulnerability has been patched in version 19.0.1.

Vulnerability details: This update includes 1 security fix. Below, we highlight fixes that were contributed by external researchers. Please see the Chrome Security Page for more information.
