A flaw was found in chromium-browser. Due to improper input validation in the FileSystem component, a remote attacker can convince a user to visit a specially crafted HTML page to achieve arbitrary code execution. Successful exploitation allows the attacker to run unauthorized commands within the browser's sandbox (an isolated security environment designed to restrict application permissions).
