This release is an emergency release to fix security vulnerabilities in Tor Browser and Tor.

You should upgrade as soon as possible.

Included software

• Update Tor Browser to 9.0.7, which prevents JavaScript from sometimes being enabled in the Safest security level of Tor Browser.

• Update Tor to 0.4.2.7, which fixes TROVE-2020-002, a major denial-of-service vulnerability that affects both Tor relays and clients. Using this vulnerability, an attacker could cause Tor to consume a huge amount of CPU, disrupting its operations for several seconds or minutes, and create patterns that could aid in traffic analysis.

• Update Thunderbird to 68.6.0.

Known issues

None specific to this release.

Tor is aware of a technical issue that allows JavaScript execution in the Safest security level of Tor Browser in some situations.

Until then, do the following to completely disable JavaScript instead of setting the security level:

1. Open the address about:config in Tor Browser.

   

2. Click the I accept the risk! button.

3. At the top of the page, search for javascript.enabled.

4. Double-click on the javascript.enabled line in the results to set its value to false.

This issue will be fixed in the next release of Tails.

This release fixes many security vulnerabilities. You should upgrade as soon as possible.

Changes and upgrades

• Update Tor Browser to 9.0.6.

• Update Thunderbird to 68.5.0.

• Update Linux to 5.4.19. This should improve the support for newer hardware (graphics, Wi-Fi, etc.).

Fixed problems

• Tentatively fix Wi-Fi interfaces with Realtek RTL8822BE and RTL8822CE chipsets. (#17323)

  If you had a problem with Wi-Fi starting from Tails 4.1, please let us know whether your problem was fixed or not.

Releases

• Tails 4.2 was released on January 7.

• Tails 4.2.2 was released on January 14 (emergency release).

• Tails 4.3 is scheduled for February 11.

The following changes were introduced in Tails 4.2:

• Improvements to automatic upgrades

  We worked on important improvements to the automatic upgrade feature, which is still one of your major pain points when using Tails:

  • Until now, if your version of Tails was several months old, you sometimes had to do 2 or more automatic upgrades in a row. For example, to upgrade from Tails 3.12 to Tails 3.16, you first had to upgrade to Tails 3.14.

    Starting with 4.2, direct automatic upgrades will be available from all prior versions to the latest version.

  • Until now, you could only do a limited number of automatic upgrades, after which you had to do a much more complicated "manual" upgrade.

    Starting with 4.2, you will only have to do a manual upgrade between major versions, for example to upgrade to Tails 5.0 in 2021.

  • We made automatic upgrades use less memory.

  • We optimized a bit the size of the download when doing automatic upgrades.

• We included several command line tools used by SecureDrop users to analyze the metadata of leaked documents on computers that cannot use the Additional Software feature:

  • PDF Redact Tools to redact and strip metadata from text documents before publishing
  • Tesseract OCR to convert images containing text into a text document
  • FFmpeg to record and convert audio and video

• Open ~/Persistent/keepassx.kdbx by default when starting KeePassX. If this database does not exist yet, stop pointing to it in the list of recent databases.

The following changes were introduced in Tails 4.2:

• Update Tor Browser to 9.0.4.

  This fixes a critical vulnerability in the JavaScript JIT compiler of Firefox and Tor Browser.

  Mozilla is aware of targeted attacks in the wild abusing this vulnerability.

  This vulnerability only affects the standard security level of Tor Browser. The safer and safest security levels are not affected.

• Avoid a 2-minutes delay when restarting after doing an automatic upgrade. (#17026)

Code

• We fixed critical regressions that were introduced while improving automatic upgrades.

• We started work on making the download of automatic upgrades more robust (#15875).

• We fixed the long delay while rebooting after applying an automatic upgrade (#17026).

• In order to make the development process a bit smoother:

  • We now use the tarball with all Tor Browser langpacks (#17400), instead of downloading a complete Tor Browser for every language.
  • Our build system is now able to cache the website build.

Documentation and website

• Göktürk Yüksek improved the dd command in the expert installation scenario to display progress (status=progress) and sync on-the-fly (oflag=direct).

• We fixed the display of the output of rsync when doing a backup of the persistent volume.

Hot topics on our help desk

1. A lot of users are complaining about Seahorse failing to import public keys

2. A few people reported graphic issues, mostly #16875, but also with Nvidia Turing

3. Some users are facing issues (#17388, #17430, #17418) with some network adapter since 4.1.1

Infrastructure

• We made progress on our migration to GitLab.

• We resumed work on upgrading our CI hardware (#16960).

Funding

• We added ThinkPenguin as a partner.

• We teared down the donation campaign. We raised around 100k€ from 2 000 donations.

• We were invited to submit a full proposal for the joint grant proposal with Tor and the Guardian Project to the DRL Internet Freedom program.

• Replace the TorBirdy extension with custom settings and patches in Thunderbird that provide equivalent privacy.
