Mozilla Patches Critical Bug in Thunderbird (threatpost.com)

Posted by msmash on Wednesday December 27, 2017 @02:00AM from the fixing-things dept.

Mozilla has issued a critical security update to its popular open-source Thunderbird email client. From a report The patch was part of a December release of five fixes that included two bugs rated high and one rated moderate and another low. Mozilla said Thunderbird, which is also serves as a news, RSS and chat client, the latest Thunderbird 52.5.2 version released last week fixes the vulnerabilities. The most serious of the fixes is a critical buffer overflow bug (CVE-2017-7845) impacting Thunderbird running on Windows operating system. The bug is present when "drawing and validating elements with angle library using Direct 3D 9," according to the Mozilla Foundation Security Advisory. US-Cert said it encourages users and administrators to review the patch and apply the necessary update.

  Thunderbird is open source if that's of consequence to you. It's freely available and not paid for like Outlook. It will also store your email locally so that if you are offline you can still get your email and not rely on cloud providers to always be available to you.

  Thunderbird can two-way sync with Google Calendar and Contacts. Outlook didn't the last time I checked, although I hear it can as of the newest version.
  
  Outlook stores everything in a huge PST file; Thunderbird uses textual mbox files and a simple directory structure.
  
  Moving a Thunderbird profile (which includes all settings, contacts, mail, saved passwords, accounts, everything) from one place to another is as simple as copying the ~/.thunderbird or %appdata%\Thunderbird folder to the same place in the other user account; Outlook has to be set up from scratch every single time and have the PST files imported and the placeholder empty PST they forcibly create (again, perhaps not with newer versions) disabled and deleted manually.
  
  Thunderbird is light-years faster than Outlook.
  
  Thunderbird is open source.
  
  Thunderbird works on Linux.
  
  Thunderbird is free as in both beer and freedom.
  
  Thunderbird has better view options, a simpler interface, a massively better heuristic junk mail filter, way nicer IMAP integration (none of that strike-through nonsense when you delete mail), and it even handles RSS feeds extremely well.
  
  Relative to Gmail, it's a local mail app so it's much faster to work with, it's less confusing that Gmail, the icons for everything are clearer than the stupid decisions made by Gmail, and the folder organization is much easier to use than the brain-dead "labels-as-folders" in Gmail.
  
  The message filter capabilities are way better and more useful than both Outlook and Gmail, the search functionality is more robust than both, and searches can be saved as "search folders" that dynamically build based on a desired search.
  
  I could go on, but I think you get the idea. Source: used Thunderbird for roughly a decade, converted many businesses to it despite external pressures to use Outlook.
  
  Oh, one tip: if someone sends an Outlook-specific winmail.dat email to you, get the LookOut extension for Thunderbird and it'll let you view it as a normal email.

  To me it does. I don't like webmail. I like to have a locally executed email client with locally cached email. Since I don't use Windows, and thus don't run Outlook (which is a joke of an email client any way, if you're not using Exchange), I have not much modern options any more. Thunderbird is basically the email client use when you prefer the open source solutions. Thunderbird seems to be the best choice, and the fact that it was a bit neglected by Mozilla had the added advantage that they didn't fuck it up as badly as Firefox.
  Well, they still did... I still wonder what was wrong with simple menus. The hamburger menu is just so dumb on desktop applications. (Hell, even on mobile it's just a cop-out)

  Anecdotal: Outlook crashes/hangs/just stops communicating with the internet on a somewhat regular basis, though I can't say it's a daily occurrence where I work. In a company of 30-50, it seems I need to fiddle with something on someone's computer once every few days. Also very aggressive about trying to use IPv6, even on a network that does not have it enabled, and takes ages to launch with large (multi-GB) PST files (though it is not as bad as it was many years ago). We had one fellow whose instance would reliably crash the first time it was launched, every single day, even after uninstall/purge/reinstall; no cause for that was ever found. Several of my coworkers, as well as myself, run Thunderbird, and nobody has reported any issues whatsoever. Regarding gmail (as a web service), it's very nice to be able to access all of your e-mail while completely disconnected from the Internet... webmail is nice, but completely useless when your Internet sucks. Gmail does support IMAP/SMTP, which I use at home (though via SeaMonkey, mostly for the heck of it).

  I don't think Thunderbird is receiving the WebExtensions architecture. At least, I have heard nothing of that sort. Mozilla has basically stated that they're leaving Thunderbird alone and I think that's a good thing. While WebExtensions may be appropriate for a browser long-term, Thunderbird is not a browser and the added capabilities of "legacy" extensions to latch into deeper parts of the Thunderbird framework are arguably far more important than on Firefox.

To send a full message source to Spamcop's web interface, I just hold CTRL and go U, A, C, W, release CTRL, then ALT+TAB to Firefox and CTRL+V in the text box.
  
  Since Thunderbird is based on Firefox's runtime, things like CTRL+[scroll wheel] zoom the contents of the message body as expected. If some asshole thinks it's funny to send 7-point light grey text (every unsubscribe line in every marketing email ever) you've got an easy way around that.

  Thunderbird contacts can do mailing lists. Using the Mail Merge extension as described here you can send letters to those mailing lists using auto-filled variables; no need for third-party programs to send emails to a small mailing list.

  I can't say what you should be doing, but I can explain why it might be a good choice for someone else.
  First, most people shouldn't be hosting their email at Google. And if you're not doing that, then using Gmail doesn't make any sense at all.
  Second, Outlook has only been ported (AFAIK) to MS Windows. If you aren't using MS Windows, then using Outlook doesn't make sense (whatcha gonna do, run it inside of WINE?). And really, I don't think I have ever heard anyone say anything particularly noteworthy about Outlook (neither good things nor bad things). (Does it have anything going for it? Any downsides, other than the Microsoft dependencies?)
  So it comes down to T-bird trying to compete with various other email clients. You might prefer one of the others (e.g. claws). But Gmail and Outlook aren't even in the running, unless you've made some other mistake with your email hosting or the OS that you run.

  Have been using it for at least 10 years. It's far more stable than the Windows *** Express or Mail clients with commercial email providers (IMAP works fine, as does POP if the provider supports it - AT&T POP support stopped working about a week ago, and gmail afaik never had it).
  The flurry of patches seems to indicate that Mozilla (or somebody) has finally started maintaining it again. It was a credible Outlook competitor (absent Exchange integration) a while back, but Outlook moved on and Thunderbird didn't. For me, using a mail client is more flexible than webmail, and more responsive. Plus, calendar integration works better with clients, and the Lightning calendar extension (which better make it through the WebExtensions conversion!) works pretty well. The other Thunderbird extension I use that is critical is Enigmail - much better integration with Thunderbird than with Outlook.

  It should not matter. If you are serving your mail from a functioning imap service, you should be able to have multiple views onto that service from different programs on multiple machines. You don't need the gmail web mail client to view email hosted by Google. You can use either or both of a client program and the web interface.

  In addition to using it to access my principal email ISP via IMAP/SMTP, I use Thunderbird to manage my gmail accounts (likewise, via IMAP/SMTP). I use the Lightning add-on to manage the Google calendars people add me to. Just because other people choose to use gmail doesn't mean I should be forced to. At least, that's how I feel about it.
  In the past I've used Thunderbird (again with the help of Lightning, plus another add-on) to manage email and calendars on corporate Exchange servers. Don't even get me started on Outlook. From my experience it was always an awful beast since the very beginning, not that I keep a close on eye on it anymore.
  So what's it going to be? Outlook? Gmail? Huh?! For every new job or new client, am I supposed to switch to a different email and calendaring UI? No thanks! If I already have one tool that's appropriate for the job at hand, why would I want to invest time in another? It's not like I engage in email and the scheduling of meetings as hobbies! They're tiresome parts of my job for which I simply need reliable tool(s). No garage is going to force a mechanic to use the "house" spanners and sockets. I don't think any homebuilder is going to force carpenters to use the corporate framing hammers.
  Thunderbird is a great tool that only ever grows dull in the sense that it's boring--because it works and stays out of the way.
  So thanks, Thunderbird! A faithful and constant part of my toolkit for over a decade. Thanks to you, I've gotten my work done with fewer needless distractions. And thanks to you, I haven't had to use those other "free" sets of tools that aren't truly free in the ways most important to me.
  Well, those are some reasons I use Thunderbird.
  They would be perfectly good reasons to use a different free and open email & calendaring client, if there's another you prefer... or can even find. Anyway, I'm sure some people can think of reasons they don't like Thunderbird. But it's familiar, works almost perfectly, and keeps my email and calendar separate from my web browser, which helps me stay organized.
  Now that they're reviving the bird, I sure hope Lightning gets updated to work with the new add-on system, and some bug fixes as well. Given the miracles they've just performed in reviving Firefox, I'm more excited than worried.

When Thunderbird was fresh and new I moved to it because it had an interface I really liked, it stored messages in mbox files I could access with any text editor if needed and it provided config capabilities and some add-ons that let me tailor it to my preferred way of working with email.
Sadly, a while back they started destroying the interface I preferred and making changes to the software that made configuring it and getting the add-ons I like to run a real problem. Thankfully there were alternatives to pick from and I did.
I switched to FossaMail years ago and have never looked back. Unfortunately, FossaMail is no longer supported, so no security updates (but also no chance to muck it up either).
The lack of updates doesn't hurt me as bad as some since I only view messages as plain text by default (short circuiting one of the paths for crap to invade a system) and I'm damned careful about what attachments I'll open. I won't click on links without knowing where they lead, which improves my security quite a bit over the average user. I should be able to safely use FossaMail for some time to come.
I certainly hope that there will still be VIABLE alternatives when the time comes to search for a new client. First, and foremost, on my list is storing the messages in text files. Also, an interface I prefer to use, not what some Outlook or Google fan boy thinks I should be using.
I sure as hell ain't gonna use that piece of crap called Outlook. So much is wrong with that software that I'd rather revert to a command line and use Pine or Mutt for a client than even think about using Outlook.

Mozilla is now a political org that makes tech by Anonymous Coward · 2017-12-27 05:53 · Score: 0

Which is a big reason why Firefox failed for the last several years. They are more interested in pushing a political agenda than building great FOSS.
They were talking about forming a membership program to support them. I have used Firefox for over ten years and I would never pay this circus a penny.

Mozilla said Thunderbird, which is also serves as a news, RSS and chat client, the latest Thunderbird 52.5.2 version released last week fixes the vulnerabilities.
Editors, please at least read what you allow to be posted.

Mozilla devs: "What's Thunderbird?" by Anonymous Coward · 2017-12-27 07:15 · Score: 0

I run Thunderbird for my personal e-mail because the alternative options aren't pretty and I can do View Source on any e-mail and get full original e-mail headers with the original message body. I am also able to completely turn off HTML e-mail, which is the primary source of malware. HTML e-mail should be completely banned worldwide as broken technology. I have to run Outlook at work, which is far more dangerous than any other piece of software you could run, including malware.
The most annoying thing about Thunderbird is that it frequently lets me know that it has "downloaded 4294967295 messages" and has been a known bug since forever. It's embarrassing when you consider that any developer could easily design a better e-mail retrieval script *without* that bug.

I've been using this since it was pine. I can fetch several accounts to my local inbox, and if I need to check it remotely it's an SSH away.
Simple and fast will never go out of style for me. You can keep your webmail and bulky email clients.

I Ignored it and it Went Away! by TechyImmigrant · 2017-12-27 08:30 · Score: 1

XUL and related stuff came along and I completely ignored it and hoped that it would go away. I pined for a simpler time when you wrote your programs, plugins, extensions and add-ons in a normal programming language.
XUL has gone away.
So I saved a whole bunch of effort. Yay.

Jody, thanks for the information.

Only the 5th sentence is not completely serious:

You think logically. You gather details. You see the big picture. You communicate clearly. I suggest that, in 2020, you run for President of the United States.

If your mom is anything like my mom.... good luck! Unfortunately, I have no solution for you there.
My brother convinced my parents to get a Mac, because you know...it just works and is easy to use. :|
problem1: he has very little understanding of computers, but thinks he's a genius
problem2: my parents have less understanding, and do all of about 3 things on their computer. Yet they still have all kinds of issues because they don't understand the basics... "Firefox, foxfire - whatever... I just need to check my Facebook and email." They use Thunderbird, but call it Firefox email.
I was there a month ago, and I noticed that there were LOTS of pending updates. I asked mom about them, and she said "yeah, that always pops up... I don't know what it is, I just close it"
To be fair, they are in their 70s and just can't keep up with the advances of technology.

To be fair,they use Linux.. So, the updates are managed by the package manager. I told them to click to install them every time it asks. Should I see they cease to do that, I’m configure totally automatic updates. I can always get on their machines using ssh, any way.

That's what is needed: Intelligent leaders. by Futurepower(R) · 2017-12-29 04:51 · Score: 1

It's okay if you don't want to be a leader in government. We need smart people like you to be leaders in every area of life.

Now there are many situations in which someone who doesn't think carefully gets a lot of money to be elected from an organization that wants favors that are bad for most citizens and destructive to the organization of the country in general.

It takes years for someone to teach herself how the government works, on any level. So, maybe 3 years until you teach yourself enough to be a candidate for the House of Representatives? -- (Smiles)
