Technical details

An integer overflow in V8, Chrome's JavaScript engine, permits remote code execution within the sandbox. The vulnerability is triggered via a crafted HTML page sent over the network, requiring only that a user visit a malicious site—no authentication or special user interaction beyond that is necessary. An attacker gains arbitrary code execution within the browser's sandbox environment.
