Google Adds V8 Sandbox To Chrome To Fight Against Browser Attacks

TLDR:

  • Google has added the V8 Sandbox to Chrome’s Vulnerability Reward Program to enhance security.
  • The sandbox helps prevent memory corruptions and logic bugs in the V8 JavaScript engine.

A Sandbox is a protective medium that blocks the entire system from any application accessing vulnerable resources. After years of development, the V8 Sandbox—a lightweight, in-process sandbox for the V8 JavaScript engine—has advanced enough to be included in Chrome’s Vulnerability Reward Program. This marks an important step towards becoming a strong security boundary. The V8 Sandbox is designed to prevent memory corruptions and logic bugs in the JavaScript engine, enhancing browser security.

Issues with current memory safety limitations are not being prevented by something, but this new mechanism prevents V8 memory corruption from affecting other processes required for optimizing the JavaScript engine. The sandbox replaces vulnerable data types and prevents memory access outside of them, adding a layer of security to Chrome browsers.

Overall, the addition of the V8 Sandbox to Chrome represents a significant advancement in browser security, offering protection against browser attacks and enhancing the user’s online safety.
