Tails 6.1 Release: A Solution to RFDS Intel CPU Vulnerabilities and Additional Bug Fixes

The amnesic incognito live system, Tails 6.1, a portable operating system providing protection against surveillance and censorship is now ready for download. This represents the first update to the latest Tails 6.0 series.

Tails 6.1 arrives one month following Tails 6.0, built on the most recent Debian GNU/Linux 12 “Bookworm” operating system series, and delivers Tor Browser 13.0.13, an anonymous web browser, and Mozilla Thunderbird 115.9.0, an email and calendar client.

Deep down, Tails 6.1 incorporates patches targeted at mitigating the newly unveiled RFDS (Register File Data Sampling) security weaknesses found affecting Intel processors. Therefore, users are highly encouraged to either update their Tails 6.0 systems to Tails 6.1 or download and utilize Tails straight from a USB flash drive.

“Register File Data Sampling (RFDS) represents a microarchitectural vulnerability, which, under certain circumstances, can potentially allow an adversary to deduce data values used previously in floating point registers, vector registers, or integer registers. RFDS only affects Intel Atom processors,” as per Intel’s security advisory.

This release also updates the Welcome Screen app to no longer show the “Welcome to Tails! is not responding” error all the time, updates the Videos app to no longer show an error message during playback, and fix problems that users encounter when changing the passphrase of a Persistent Storage.

On top of that, Tails 6.1 improves the Onion Circuits, adds support for Tails Cloner to install and upgrade to devices that contain multiple mounted partitions, and updates the Persistent Storage settings to display all enabled custom Persistent Storage features.

Tails 6.1 is available for download right now from the official website as an ISO image that you can use to install Tails on a virtual machine or as a USB image that’s recommended for running Tails live from a USB flash drive. Existing Tails 6.0 users will be automatically updated to the new release.
