Cisco has released a Security Advisory to address a vulnerability that affects Cisco Webex Meeting Manager. This vulnerability is due to a buffer overflow condition in the "NewObject()" method within the WebexUCFObject ActiveX control (atucfobj.dll). By convincing a user to visit a specially crafted web page, open an e-mail message that contains embedded malicious HTML code, or by sending malicious HTML code via instant messaging applications, a remote attacker may be able to execute arbitrary code.
