The above statement is all wrong. Thunderbird by default displays emails
as original HTML. Only when you install TorBirdy does that change.

 This is why it was considered a moderate security issue.

No, I don't believe that played any part in the classification.

 It isn't a drive by exploit where you send mail to people and then
 something happens to them. They have to actively cooperate to be
 exploited.

It requires the user to receive an email, and then click a link in that
email. This is not unusual behaviour.

 It is a bug, yes, but it isn???t as bad as was being painted the other day 
 here.

It is a horrible bug for Tor users who are using Thunderbird without
TorBirdy. To clarify, at no point did I state that TorBirdy users were
affected. I brought up the issue here exactly so that those sorts of
issues could be investigated.

I suggest if you are going to make any further statements about the
way the bug works, you replicate it first.

The bug report is now public. Somebody has submitted a patch, but
they've also suggested that there may be similar bugs in the MathML
code waiting to be found.

If somebody put my name in quotes, I wouldn't immediately jump to the
conclusion that they're claiming that it isn't my name, nor would I
care. But then I wouldn't go around making incorrect claims about bugs
without testing them first either. I'm sorry if I hurt your feelings
by pointing out that you were wrong on your employers bugzilla board,
but it's your own fault for not backing up your claims. Unless you've
got something useful to add regarding the bug, please don't continue
adding noise, on this list, or on the bugzilla page. All you've done
so far is confuse matters.

I wont be taking part in this thread on tor-talk any further. If anyone

Security related bugs are hidden by default and only made public when
a fix is rolled out. This is very common. They are aware that this issue
is now public information so I assume they'll be unlocking it at some
point.

Unfortunately, in this instance, I think this private disclosure has
allowed the issue to go unfixed for a long time. I probably should have
made it public much sooner.

For me it was enough to do this on a Thunderbird Unix Mailspool
(Movemail) account (Settings/Account Actions/Add Other Account...):

$ cat | sendmail -t
From: $YOUR_USER
To: $YOUR_USER
MIME-Version: 1.0
Subject: Test
Content-Type: text/html

html
  body
svg xmlns=http://www.w3.org/2000/svg;
xmlns:xlink=http://www.w3.org/1999/xlink; version=1.1

text x=0 y=12 font-family=Verdana font-size=12
fill=blackClick me/text
  /a
/svg
  /body
/html

[CTRL]+[D]

Though I don't know whether it makes a difference to use unix mailspool
instead of a normal IMAPS/POPS:

When I opened that email and set View/Message Body As/Original HTML,
Torbirdy did not prevent the tab to load nor refuse to display the HTML.
(Maybe this is intended, because Torbirdy only focuses on normal email
accounts(?))

So, by default, users will not be automatically exploited. They have to get a

No, this is not related to the type of emails accounts but because you
explicitly asked Thunderbird to display the message in its original HTML
form and thus were able to reproduce this behaviour. If TorBirdy is
enabled, it will convert the HTML to plain text (sanitizing it) before
displaying it.

Just to clarify: Thunderbird does the HTML sanitization, not TorBirdy.
TorBirdy just makes sure that the relevant preferences are enabled and
enforced.

I just blogged about a general security issue in Thunderbird which may
also affect people who are using Tor:

Basically, an email can be crafted such that when you click a link in
that email it is opened within a Thunderbird tab instead of in your

you might also have, including NoScript etc.

As mentioned in the blog post, when right clicking one of these links
in order to select Copy Link Location from the context menu, you will
find that the option is missing. I imagine that many people at this point
would skip their usual copy/paste routine and just click the link for

You're definitely not supposed to be able to do this. Mozilla
acknowledged that it was a security issue and classified it as moderate.
It has been over two years since I told them about it and it hasn't
been fixed, hence why I am now making it public.

Re: [tor-talk] Thunderbird leak

2014-01-26 Thread Sukhbir Singh
This issue does not affect TorBirdy as it disables HTML emails. From [0]:

emails you send will be in plain text and HTML emails you receive
will be sanitized and converted to plain text.

(I have tried to reproduce this leak and can confirm that Thunderbird
+ TorBirdy is not vulnerable.)

Assuming we’re talking about people opening web pages in TB tabs, that normally 
can only happen if someone installs Thunderbrowse or a similar extension. By 
default, TB doesn’t render web pages.

  I just blogged about a general security issue in Thunderbird which may

  Basically, an email can be crafted such that when you click a link in
  that email it is opened within a Thunderbird tab instead of in your
  usual (potentially torified) web browser. Bypassing any other defenses
  you might also have, including NoScript etc.

The woes of HTML E-Mail...

 You're definitely not supposed to be able to do this. Mozilla
 acknowledged that it was a security issue and classified it as moderate.
 It has been over two years since I told them about it and it hasn't
 been fixed, hence why I am now making it public.

I thought the same thing.  I'm pretty sure I've had links in email open 
IN Tbird tabs.  It happened so rarely, took me by surprise. For safety, 
I never really clicked links in email.  After that, I never do.
I'm guessing it may've been a confirmation email for website forum, tech 
support w/ a link, etc.  Something I expected, or likely wouldn't just 
have clicked it, regardless of what Tbird's supposed / not supposed to do.


Of course, NSA could've intercepted the real confirmation  sent a link 
that downloaded malware.


If R click  copy link location was missing, I'd not click it at all, 
or erase msg or at bare minimum (if it was important), look at the msg 
source to see the real link.
When you're tired, may not realize you're in email  absent mindedly 
click a link.  Rather than a browser - where it's common to click links.

Something to be said for using email text only mode.

Like I said, Thunderbird doesn't allow for pages to open in tabs without an
extension. So., if you have reliable repro steps,  it is a bug that should
be fixed and I can push on it to get it addressed.
