A flaw was found in Google Chrome's Privacy component. Due to improper input validation, a remote attacker could convince a user to visit a crafted HTML page to execute arbitrary code outside the browser's security sandbox (an isolated execution environment). Successful exploitation could allow the attacker to bypass security boundaries and compromise the underlying system.
