Hm. Looks like their listing is for the first issue of 2007-009 only. V 1.1 was released a few days later. S'pose they don't consider the revision worth mentioning. Hopefully that's good news, i.e., it was just Safari.
On first glance, they're just giving the standard-issue warning, same as Apple does. Of course, e-mail alerts are always good. But I wonder if US-CERT would publish any more than what Apple tells them.
