Tor Browser 4.0.8 is released

by mikeperry | April 9, 2015

A new release for the stable Tor Browser is available from the Tor Browser Project page and also from our distribution directory.

This release contains a fix for the update loop issue present in 4.0.7. It is otherwise identical to that release.

Both 4.0.7 and 4.0.8 contain an update to the included Tor software, to fix two crash bugs in the version of the Tor software included prior to 4.0.7. One crash bug affects only people using the bundled tor binary to run hidden services, and the other crash bug allows a malicious website or Tor exit node to crash the underlying tor client by inducing it to load a resource from a hidden service with a malformed descriptor. These bugs do not allow remote code execution, but because they can be used by arbitrary actors to perform a denial of service, we are issuing a security update to address them.

There will be no corresponding 4.5-alpha release for this fix, to allow us to focus on stabilizing that series for release in ~2 weeks.

Note to MacOS users: This is the last planned release that will run on 32 bit MacOS versions. Users of Mac OS 10.8 (Mountain Lion) and newer versions will be automatically updated to the 64 bit Tor Browser 4.5 when it is stabilized in April, and we expect this transition to be smooth for those users. However, the update process for 10.6 and 10.7 users will unfortunately not be automatic. For more details, see the original end-of-life blog post.

Here is the complete changelog since 4.0.6 (covering 4.0.7 and 4.0.8):

All Platforms
- Bug 15637: Fix update loop due to improper versioning
- Update Tor to 0.2.5.12
- Update NoScript to 2.6.9.21

Hijacked Firefox browser ..new install! Made a post using Tor and Got a security threat that took over firefox and My DNS! when I cleaned Firefox..it pointed to a joining of Tor with Firefox that my firewall killed all connection! had to do a backup and a browser reinstall!

Are you perhaps getting the stable Tor Browser 4.0.x versions confused with the experimental Tor Browser 4.5.x versions?

Usually alpha and stable updates are released almost simultaneously. So, yes, to your first question. 4.5 should be the new stable next week or the week thereafter.

It's fine to have signatures

It's fine to have signatures from keys you've never heard of or can't fetch.

It's the keys that you *can* fetch, and consider trust in, that you should be looking at.

i feel Alpha version is faster and lighter than stable version !Does someone else has experienced it?

Me 2 do agree with U

I absolutely love the new

I absolutely love the new feature of running Tor as a VPN on Android. We totally need this feature on PC too!

me too

Having Tor function

Having Tor function similarly to a VPN is a dangerous route, given that a major reason for such a setup is to allow users to use software that does not have or respect proxy settings to be routed through Tor. Software like that (if it's closed source) could easily be designed to NOT use a VPN connection and use methods to connect directly without going through the VPN-like Tor.

My Tor asked me if I wanted

My Tor asked me if I wanted to update to 4.08. I chose to accept. It then installed. I also saw under the Window menu a "software update" option.

I found it a bit suspicious later because I thought you could only manually update directly from the website. I decided to then reinstall 4.08 by downloading straight from the website. All of a sudden I no longer see a "software update"option under the Window menu... only 'minimize' 'zoom' and 'about..' Should I be concerned that the auto-update I initially experienced was not a legitimate software bundle? Was I hacked?

I viewed a pop up window

I viewed a pop up window that asked to update to 4.08. I did. Then tor browser would not run. The error message is XPCOM will not load.

This probably is a dumb

This probably is a dumb question (on this blog with many savvy posters). I installed the latest version (4.0.8) today and, unlike with prior new updates, couldn't figure out how to change the home page to one I prefer. Please help. Thanks.

Question on the preferred

Question on the preferred way to update:

TBB can be updated in-place via Help -> About Tor Browser (works similar to how regular Firefox will update itself in-place.) After this in-place update, About Tor Browser reports the current correct v4.08. However, plugins must then be manually checked/updated.

Is this process the same as / better than / worse than "updating" TBB by downloading and running the "torbrowser_install_xxxx.exe" package? How should TBB updates be correctly performed?

I'd say it's about the same.

I'd say it's about the same. The only exception might be if you want to verify signatures before installing a 4.0x package. In that case, you'd have to download the bundle in order to verify it. In 4.5x, I think (but am not completely positive) it's going to have signature verification built into the self-updater, so at that point there will be even less of a difference between the two update methods.

A very good question! Please

A very good question! Please answer on this, thanks!

Is it okay for me to update

Is there a way to enable "limited script" for Tor users? This would allow Javascript that makes a web site function properly but disable any code that accesses identifying information. It is likely that Facebook is identifying Tor users which would make it easier to identify everybody else.

Another idea is to give priority to users of little bandwidth over users who are using massive amounts.

And another thought: I suspect that major email providers are blocking clearnet emails from darknet email providers. Even if they are allowed through in some cases, the darknet email providers need to have a delayed send feature. Otherwise the timing of Tor access can be correlated with the timing of an email.

While not specifically an add blocker, disabling javascript can significantly reduce the number of popups. Have you changed how you're using noscript? Also, are you sure that the website(s) in question haven't changed behavior?

Appeal to Tor

Appeal to Tor developers:

Please elect a scripting language/programming language to replace java/javascript and continue to build on that..

we cannot trust java
as a user we have very little control of java apart from disabling it with noscript in the browser

what would be nice (not making this Tor developers responsibility here), is a sort of app-firewall/apparmor for java or a COMPLETELY security safe java-like to replace the existing java which is being rammed down our throats; java is being used because developers (java) are lazy and want to code once, well guess what python, perl etc also runs on many platforms...

Its simply a contradiction here, Tor users are "advised" to use noscript to disable javascript yet developers continue to expand on its use especially with the Tor apps.

No; Java (which uses the Java Virual Machine) and Javascript (which doesn't use the JVM) are not in most cases interrelated. Yes, you can use javascript to for some (extremely limited) control of java applets, but from a security standpoint they are two very different technologies. Please, research the issue before posting; there's plenty of information on the web about Jav and Javascript and the difference between the two.

but javascript seems to be associated with popups, adsite on a page, loading adsite for every godam webpage these days I know noscript deals with lots of things.
nothing personal, but I have no interest in either i just want the page from the domain I'm browsing.

thankyou for clarification

no-java Anon

From Torbrowser's

From Torbrowser's perspective, ads and popups are near to the end of the list of concerns from javascript. They're not at the end but they make tracking easier. Of course you don't need either of them to track with javascript, and there are more dangerous things than tracking that javascript can accomplish.

I appreciate that Tor

I appreciate that Tor developers have core pieces to look after
security is important but, from our perspective, popups and ads are *king nuisance have spoilt the internet experience
i dont care about ads helping to finance something, get a million billion dollar corporation to pay for it, same logic as food packaging don't make it the consumers problem get the manufacturers to comply thats the source of the problem.
remove porn, ads, popups, marketing depts pull push bs and we would have a better world.

First of all, Java =/=

First of all, Java =/= Javascript; in fact, they're not remotely related from a technical standpoint. Javascript was originally named livescript but was remained to Javascript for marketing reasons after the first Java plugin was made for Netscape (some type of 'wave' of "Java-" technologies.)Second, Tor project developers are hardly ramming javascript down anyones throat. Sure, the web is more and more dependent on javascript every day, but it's not like someone can simply write a replacement for javascript and expect all the web developers to move over, especially when a scripting language is only supported by it is only supported by one browser. Microsoft tried that with vbscript back when IE held far more of the market share and they failed. That's not even mentioning the fact that coders would have to recode everything and despite what you think, that's a substantial job especially given they'd have to learn a whole new language to code with. In addition, any new language, like any new piece of software, is going to be buggy; such a solution is going to add to the number of security vulnerabilities in the initial period. That's where a good number of the Javascript security threats are: bugs. A new scripting language is simply adding to that problem; sure, Javascript was not designed with all of the threats that Torproject thinks about but those threats aren't the only or even primary reason to disable Javascript. Yes, disabling Javascript is the easy answer (Torbrowser contains patches to make Java itself incredibly hard to enable,) but that's because for most users that all they need to know. However, if you're going to give actual suggestions or make appeals it might be a good idea to know what you're actually talking about. It may be cool to jump on the Javascript hating bandwagon, but if you don't know why you're there you really aren't in any place to give advice.

further web

further web searches
netscape called it javascript for marketing purposes but has no relation to java (and jvm); intention was to confuse with the jargon and its still called javascript to this day.
alternate names -jscript even suggests 'Java', or its original 'ecma'
without javascript enabled on a webpage we get just the main content, i have no all interest in scorecardsearch, adtech, every other useless adsite popups and related (thank god for noscript)
I think most people would agree we can do without the crap bolted on or called by javascript on just about every website these days = "rammed down our throats". my earlier comment doesnt say nor did I suggest it was just Tor browser teams its webadmins everywhere, surfing the web is not as pleasant experience as it was decades ago.
thankyou Tor developers for the great work.

no-java Anon

First of all, popup ads

First of all, popup ads aren't nearly as bad as they used to be. After several years of most browsers having some limited form of blocking, their prevalence has definitely decreased as they aren't worthwhile from a revenue prospective. Second, javascript does far more than just ads. In fact, that's why in most browsers you can't simply disable it like the old days. Firefox (and therefore Torbrowser) uses javascript internally to do a whole bunch of things; it wouldn't work without javascript. Of course, that's separate from javascript from external sources.

thankyou for your explanations

no-java Anon

Software being buggy is a

Software being buggy is a very good reason not to use it when dealing with security; Javascript bugs are after all the number one reason to disable javascript. A bug in a webbrowser can easily be exploited to do a whole number of nasty things, like infecting your system with a trojan.

technology comes and goes all the time, entire websites are rewritten all the time how is that different from any other week, month?!

no-java Anon

Yes, and every line of code

Yes, and every line of code can be buggy and that bug could be exploitable. Of course, that's true with old code as well, but the old code has had time for people to find the bugs. By the way, entire websites aren't rewritten all of the time. Most major (big) websites are significantly compartmentalized and they change one piece at a time; they don't throw out the whole thing and start over unless they have too.
But that's missing another major point: Any replacement for Javascript that handles most of the use cases for Javascript is going to have the same problems as javascript. It's not like we don't already have several different implementations of javascript already.
