Tails OS 4.2.2 releases: fixes a critical vulnerability

Tails OS is a live operating system that you can start on almost any computer from a DVD, USB stick, or SD card.

It aims at preserving your privacy and anonymity and helps you to:

• use the Internet anonymously and circumvent censorship; all connections to the Internet are forced to go through the Tor network;
• leave no trace on the computer you are using unless you ask it explicitly;
• use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.
