[Secure-testing-team] Bug#607497: midori: Loads HTTPS with SSL errors without any notice

[Witold Baryluk]

Package: midori
Version: 0.2.7-1.1
Severity: grave
Tags: security squeeze
Justification: user security hole

Simple example

Go to https://turtle.libre.fm/
(this site have expired ssl certificate, and it is issued to other domain).

Address bar in midori will go red, yes, but there is no way to see what is
wrong.
(One can use wget or openssl sclient ... or other browser)

What is worse, midori actually loads this page and shows us a page.

It should block request, and should not make connection so easy.
(IMHO there should not even be a way to bypass this errors).

Possible private data leakage:
  - cookies
  - private urls
  - logins, passwords data
  - confidential informations on page.

This bug makes MITM attack quite simple.

Yes, user will notice this (becuase of red address bar), but it will be already
to late to do anything - data was already sent and received.


Thanks.
