[Tails News] Tails 6.11

# [Tails 6.11](https://tails.net/news/version_6.11/index.en.html)

# Critical security fixes

The vulnerabilities described below were identified during an external
security audit by [Radically Open
Security](https://www.radicallyopensecurity.com/) and disclosed responsibly to
our team. We are not aware of these attacks being used against Tails users
until now.

These vulnerabilities can only be exploited by a powerful attacker who has
already exploited another vulnerability to take control of an application in
Tails.

If you want to be extra careful and used Tails a lot since January 9 without
upgrading, we recommend that you do a [manual
upgrade](https://tails.net/upgrade/index.en.html#manual) instead of an
automatic upgrade.

* Prevent an attacker from installing malicious software permanently. ([#20701](https://gitlab.tails.boum.org/tails/tails/-/issues/20701))

In Tails 6.10 or earlier, an attacker who has already taken control of an
application in Tails could then exploit a vulnerability in _Tails Upgrader_ to
install a malicious upgrade and permanently take control of your Tails.

Doing a [manual upgrade](https://tails.net/upgrade/index.en.html#manual) would
erase such malicious software.

* Prevent an attacker from monitoring online activity. ([#20709](https://gitlab.tails.boum.org/tails/tails/-/issues/20709) and [#20702](https://gitlab.tails.boum.org/tails/tails/-/issues/20702))

In Tails 6.10 or earlier, an attacker who has already taken control of an
application in Tails could then exploit vulnerabilities in other applications
that might lead to deanonymization or the monitoring of browsing activity:

    * In _Onion Circuits_ , to get information about Tor circuits and close them.
    * In _Unsafe Browser_ , to connect to the Internet without going through Tor.
    * In _Tor Browser_ , to monitor your browsing activity.
    * In _Tor Connection_ , to reconfigure or block your connection to the Tor network.
  * Prevent an attacker from changing the Persistent Storage settings. ([#20710](https://gitlab.tails.boum.org/tails/tails/-/issues/20710))

# New features

## Detection of partitioning errors

Sometimes, the partitions on a Tails USB stick get corrupted. This creates
errors with the Persistent Storage or during upgrades. Partitions can get
corrupted because of broken or counterfeit hardware, software errors, or
physically removing the USB stick while Tails is running.

Tails now warns about such partitioning errors earlier. For example, if
partitioning errors are detected when there is no Persistent Storage, Tails
recommends that you reinstall or use a new USB stick.

your Tails USB
stick.](https://tails.net/news/version_6.11/partitioning_errors.png)

# Changes and updates

* Update _Tor Browser_ to [14.0.4](https://blog.torproject.org/new-release-tor-browser-1404).

* Update _Thunderbird_ to [128.5.0esr](https://www.thunderbird.net/en-US/thunderbird/128.5.0esr/releasenotes/).

* Remove support for hardware wallets in _Electrum_. Trezor wallets stopped working in Debian 12 (Bookworm), and so in Tails 6.0 or later.

* Disable _GNOME Text Editor_ from reopening on the last file. ([#20704](https://gitlab.tails.boum.org/tails/tails/-/issues/20704))

* Add a link to the _Tor Connection_ assistant from the menu of the Tor status icon on the desktop.

* Make it easier for our team to find useful information in _WhisperBack_ reports.

[changelog](https://gitlab.tails.boum.org/tails/tails/-/blob/master/debian/changelog).
