A flaw was found in Google Chrome. This vulnerability, a use-after-free error, occurs when the program attempts to use memory that has already been released, which can lead to unexpected program behavior. A remote attacker could exploit this by enticing a user to visit a specially crafted HTML page, potentially enabling the execution of arbitrary code outside of the browser's security sandbox.
