The Amnesic Incognito Live System (Tails) is a Debian-based live DVD/USB with the goal of providing complete Internet anonymity for the user. The project’s developers have released Tails 3.4 which includes kernel fixes for the Meltdown and Spectre bugs, updates uBlock Origin and includes fixes for package installation.
“Tails 3.4 is out. This release fixes many security issues and users should upgrade as soon as possible. In particular, Tails 3.4 fixes the widely-reported Meltdown attack, and includes the partial mitigation for Spectre. Changes: update Linux to 4.14.12 which fixes Meltdown, Spectre (only partially) and many other issues; fix an issue that made Tails start very slowly, in particular on DVD; don’t delete downloaded Debian packages after installing them, this is mostly relevant for users of the APT Packages persistence feature; fix an issue that prevented some Debian packages to install properly with the Additional software feature; update uBlock Origin to restore its icon in Tor Browser and make its settings dashboard work again.”
