Tor Browser 6.0.5 发布更新至Firefox 45.4.0esr 添加unpacked HTTPS-Everywhere

Tor Browser 6.0.5 is now available from the Tor Browser Project page and also from ourdistribution directory.

This release features important security updates to Firefox including the recently disclosed extension update vulnerability. All users should upgrade as soon as possible.

That vulnerability allows an attacker who is able to obtain a valid certificate for addons.mozilla.org to impersonate Mozilla's servers and to deliver a malicious extension update, e.g. for NoScript. This could lead to arbitrary code execution. Moreover, other built-in certificate pinnings are affected as well. Obtaining such a certificate is not an easy task, but it's within reach of powerful adversaries (e.g. nation states).

Thanks to everyone who helped investigating this bug and getting a bugfix release out as fast as possible.

We are currently building the alpha and hardened bundles (6.5a3 and 6.5a3-hardened) that will contain the fix for alpha/hardened channel users. We expect them to get released at the beginning of next week. Until then users are strongly encouraged to use Tor Browser 6.0.5.

Apart from fixing Firefox vulnerabilities this release comes with a new Tor stable version (0.2.8.7), an updated HTTPS-Everywhere (5.2.4), and fixes minor bugs.
