SA11966 is from a year ago and has had a solution for about as long.

Firefox/Mozilla have apparently reintroduced this bug recently and thus the
repost of the vulnerability.

Please read the link provided above. Here is an excerpt:

The vulnerability has been confirmed in Firefox 1.0.4 and Mozilla 1.7.8.
Other versions may also be affected.
 
The vulnerability has been confirmed in Firefox 1.0.4 and Mozilla 1.7.8.

The bug only works if you:

1. Have Javascript enabled, and:

2. Open new windows when clicking on links rather than use tabbed browsing.

Seeing how some sites force new windows to open, it's a concern, but not a
large one.

From the above site:

"Description:
A seven year old vulnerability has been re-introduced in Mozilla and
Firefox, which can be exploited by malicious people to spoof the
contents of web sites."

and

"The vulnerability has been confirmed in Firefox 1.0.4 and Mozilla
1.7.8. Other versions may also be affected."

The advisory also states to "proceed with caution". Personally I never
surf in any other fashion.

ad 1. Wrong. JS need not be enabled.

FWIW, old Netscape v4.whatever are vulnerable, too.

I failed with Firefox (Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.7.8).

Other than capturing info (not a small theft) what else could the *fake*
window do? My firewall still protects me unless I manually provide (key
in) information at a site - -Correct?

That version has the vulnerability. To make the Secunia demo work, you
have to have the browser set to open new windows instead of tabs.

It's just a spoofing vulnerability -- as long as you are not fooled
into entering info into a form in a spoofed page, no worries. If you
are ever unsure about whether a frame is legit, right click it and
choose "this frame » view frame info" to see what its URL is.

I went to Options/Advanced-- Check Open.....a new window/

I closed Firefox, even checking TaskManager to make sure it was shutdown.

I opened it (you know where this is going..) Yep, I went to Secunia and
MS and back to Secunia and their page fill the MS frame.

OH...!

Only the *frame* of a site can be screwed with (Yes, it is probably
noted in this thread...) - - I guess a good habit is no not place any
info in *any* frame...Why risk it? (Like I can tell if a frame is
legit?) No, I am not ever *not* unsure.

Thanks!

Firefox can be set to ignore what the website wants.

OK?

How?

It begs the question:
How do we know *what* any website *wants* (and how does one selectively
not provide it)?

And there's a way to force Firefox to open ALL new windows in tabs
anyway, so it's really NO concern if you have it set up that way.
 

Numerous ways. Extensions is one way.

There is a one window mode in firefox, I don't know if it strictly forces
all links to open in tabs though.

A little understanding of html,javascript etc of course.
The most obvious, links with target="_blank"
(and how does one selectively
not provide it)?

Did I say selectively? Though possible (eg firefox can open all popups in
tabs except for popups with a defined size) of course.
