Fellow PLUGgers,

I don't know how serious this bug actually is, which probably depends on
how deep it goes into the code and what other information can be leaked
out, but the demonstration page actually works and well... my initial
reaction was "wow, cool".

Not that when you return to the page you don't have to use the back
button, you can re-enter it into the address bar and it will still work,
meaning the demo page will know what URL you went to immediately after
you visited the demo page last.

Subject: Privacy leak in mozilla
From: Sven Neuhaus <[EMAIL PROTECTED]>

There is a serious privacy leak in Mozilla that reveals the URL of the
page you are visiting to the web server of the page you visited last.
The leak not only occurs for links followed on the page (that wouldn't
be particularly serious) but also for URLs entered manually or picked
from the bookmarks.

The bug affects Mozilla 1.0, 1.0.1, 1.1 and probably older versions as
well. It also affects Mozilla-based browers such as Netscape 7 and
Galeon.

The problem is that HTTP requests that are launched from a page's
"onunload" handler have the wrong referer (sic): They get the referer of
the next page the user is about to visit.

Demonstration URL:

This is bug 145579 from the bugzilla database. It's a couple of months
old now so I'm disclosing this vulnerability to hopefully initiate the
fixing process.

Workaround: Disable Javascript.

Best,
-Sven Neuhaus
