Fedora 23: 2016-1234 Critical: OpenSSH Security Update Required Now

Tor is a connection-based low-latency anonymous communication system.

Applications connect to the local Tor proxy using the SOCKS protocol. The

local proxy chooses a path through a set of relays, in which each relay

knows its predecessor and successor, but no others. Traffic flowing down

the circuit is unwrapped by a symmetric key at each relay, which reveals

the downstream relay.

Warnings: Tor does no protocol cleaning. That means there is a danger

that application protocols and associated programs can be induced to

reveal information about the initiator. Tor depends on Privoxy and

similar protocol cleaners to solve this problem. This is alpha code,

and is even more likely than released code to have anonymity-spoiling

bugs. The present network is very small -- this further reduces the

strength of the anonymity provided. Tor is not presently suitable for

high-stakes anonymity.
