Today, the MSRC released Security Advisory 2794220 alerting customers to limited, targeted attacks affecting customers using Internet Explorer 6, 7, and 8. Internet Explorer 9 and Internet Explorer 10 users are safe.
This affects all Windows XP users as neither Internet Explorer 9 nor 10 is available for this platform. Windows Vista and Windows 7 users should ensure that their version of Internet Explorer is up to date.
Until a security patch is released, all users of Internet Explorer 8 or lower are cautioned to use alternative browsers. Alternatively, disabling either Flash or Java will prevent the execution of the exploit.
