Mergs, Perhaps you missed this part of the article:
"The issue affects users of Firefox 3.0 as well as Firefox 2.0"
I did, I did. That's ok because I only use Firefox on "safe sites", like this one
p.s. good thing Tipping Point are such swell guys:
"Tipping Point has verified the bug and reported it to Mozilla, Tipping Point said on Wednesday.
Since Mozilla is still working on a fix, the researchers won't share details about the problem."
because when some of the (other) 3rd party white hats find these things, they sometimes reveal the exact steps to take advantage of the vulnerability which tends to annoy me.
