Tor Browser 3.6-beta-2 is released

The Tor Browser Team is proud to announce the second beta in the 3.6 series. Packages are available from the Tor Browser Project page and also from our distribution directory.

This release is an important security update over 3.6-beta-1. This release updates OpenSSL to version 1.0.1g, to address potential client-side vectors for CVE-2014-0160.

The browser itself does not use OpenSSL, and is not vulnerable to this CVE. However, this release is still considered an important security update, because it is theoretically possible to extract sensitive information from the Tor client sub-process.

This beta also features a Turkish language bundle, experimental Javascript hardening options, fixes for pluggable transport issues, and a fix for improper update notification while extracting the bundle over an already existing copy.

Here is the complete changelog since 3.6-beta-1:

  • All Platforms

The bug #9387 changes ("Disable JS JIT, type inference, asmjs, and ion. ") seem to involve turning off everything which is intended to make JavaScript fast.
Has there been any systematic attempt to evaluate what effect this may have on performance?
Has there, for that matter, been any systematic attempt to evaluate what additional security benefit this brings, e.g. what proportion of past Firefox vulnerabilities would users have been protected against if each of these features were disabled?

While your suggestion of going thru past issues may sound systematic and smart, the low hanging fruit for bad guys is using already disclosed -- but unfixed -- vulnerabilities. So the past is somewhat irrelevant.

Regarding speed....well that's one of the benefits of having a beta to evaluate.

I entered about:config and typed "www" or ".com" or ".org" and then there are 50 built in urls that can potentially leak information. Why are they in there?

I Remove most of them in about:config by either deleting or changing the URL. I suggest all google links are removed as those bastards are monitoring everything on the net.

Not bad not bad. I see a lot of bitching and moaning ^ but also a lot of valid points which I wont point out to you again.

People moaning about speed - Learn how Tor works
People moaning about losing addons and bookmarks after updating - What do you expect?

Keep up the good work Tor. Much love.

I'm connecting thru VPN, when I first launch the TBB should I click "connect" or "configure"?

Tor is not working at all on Win 8.1 for me now . . . it worked fine before
