Description Josh Bressers 2006-04-13 04:12:13 UTC

Mail Multiple Information Disclosure


As a privacy measure to prevent senders (primarily spammers) from tracking
when e-mail is read Thunderbird does not load remote content referenced from
an HTML mail message until a user tells it to do so. This normally includes
the content of frames and CSS files, but CrashFr showed it was possible to
bypass this restriction through indirection: the direct CSS or iframe src is
included in-line, with that including remote content.

Workaround

Switch the "view message body as..." choice to "Simple HTML" or "Plain
text". Or for POP mail, after downloading the mail switch to offline mode
before reading any of it.
