Today we released MS10-018 out-of-band due to increases in attacks against Internet Explorer 6 and Internet Explorer 7 using the vulnerability discussed in Security Advisory 981374. I want to reiterate that Internet Explorer 8 is not affected by this issue so customers using this version are not affected by these attacks and we continue to encourage customers to upgrade to the newer version because it provides more security and protection.

Mozilla has only rolled the browser out to one handset so far — Nokia’s Maemo-based N900, pictured here running the application — but it plans to create versions for the Android and Windows Mobile platforms.
