The fact that iframes are insecure in Outlook is strictly because of an
Outlook bug. (Well, an IE bug actually, but Outlook uses IE to render
HTML.) There is nothing inherently insecure about them, and Evo doesn't
have the same bug, AND Windows viruses can't infect you on Linux anyway.
So this is really a non-issue.

Its up to the image library to handle it, so yes you could exploit holes
in libjpeg or gdk-pixbuf if they existed.
The alternative is to only allow the display of text ...
Wouldn't it be possible to use the html rendering widget only for the
headers (just to get the nice box), the body of the mail gets displayed
using a text box?
Since the headers are being preprocessed anyway if you use full html
rendering, you could simply reuse the header preprocessor method, and
feed the rest of the mail to a text box.
I am sorry I can't provide a patch for this., ;)

Am I right that evolution doesn't seem to do no better than outlook when
it comes to inlined data?
If you get an email sporting a line like
and attached you get a file with a
string, evolution tries to to display this stuff inline, no?
And since most of these attachements are virus today, the user is no
better off than an outlook user?!
Please correct me, if this isn't so! But, e.g. what happens, when you
receive an email with an attachment blabla.scr, and the mime type is
audio/wav, an this file is inlined by the above tag, then evolution
tries to view (play) it (of course it's not a wav file, just look at the
file suffix, it's just some viral code)?
There is obviously no button which you could press to view the
attachement, since it's getting viewed inline. Is there any way to
prevent evolution from doing so?
