A flaw was found in Google Chrome Extensions. A race condition exists that could be exploited by a remote attacker who has already compromised the browser's renderer process. By crafting a malicious HTML page, the attacker could potentially execute arbitrary code outside of the browser's security sandbox, leading to a more severe system compromise.
