Reed,

It looks like they _may_ have updated this article, since I didn't
see this when I originally read it:

"The disclosure comes on the same day that Mozilla released an
update for Firefox, which does not address the JavaScript flaw."

Any idea what bug this may be? There aren't any critical ones that
Michal Zalewski has reported that haven't been fixed in a release.

I'm thinking the article is referring to
https://bugzilla.mozilla.org/show_bug.cgi?id=371321, which was fixed in
Firefox 2.0.0.2. However, as the article is extremely vague, it's hard
to tell what vulnerability it is reporting.

The article links to Mozilla's Bugzilla, not to the actual bug
(bug 371321). Also, it links to the CERT home page, not the actual
vulnerability notice (http://www.kb.cert.org/vuls/id/393921).

If this article is about that particular bug, the reporter is behind in
his research. ;)
