New Release: Tails 6.8.1

+++ Updated: Oct 14, 20:30 UTC +++

An earlier version of this blog post incorrectly stated that "Mozilla is aware of this attack being used in the wild against Tor Browser users." This has been corrected to accurately reflect Mozilla's official statement.

To be clear, the Tor Project has no evidence that Tor Browser users were targeted specifically. The Firefox vulnerability has since been addressed with Tor Browser releases 13.5.7, 13.5.8 (for Android), and 14.0a9.

This release is an emergency release to fix a critical security vulnerability in Tor Browser.

Changes and updates

• Update Tor Browser to 13.5.7, which fixes MFSA 2024-51, a major use-after-free vulnerability. Using this vulnerability, an attacker could take control of Tor Browser , but probably not deanonymize you in Tails.

Mozilla is aware that "a Firefox exploit that had been spotted in the wild."
