Tails 6.15.1 Emergency upgrade now! (JS fix, reminder to keep JS OFF on DN!) : Tails | Torhoo darknet markets

Tails 6.15.1
2025-05-20

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

Update Tor Browser to 14.5.2, which fixes Mozilla Foundation Security Advisory 2025-37. These vulnerabilities allow an attacker to perform an out-of-bounds read or write on a JavaScript object, but don't allow breaking out of the Firefox sandbox.

Update Thunderbird to 128.10.1.

Remove the Tor Browser and Tor Browser (persistent) folders: they are not necessary anymore, thanks to the more flexible confinement of Tor Browser we introduced in Tails 6.14.1. (#15028)

Fixed problems

Fix the Unsafe Browser appearing in the window list with the Tor Browser icon. (#20934)

Make reporting an error using WhisperBack more robust. (#20921)

Fix USB tethering. (#20940)
