Tor: Information disclosure A flaw in Tor leads to the disclosure of information and the loss of anonymity, integrity and confidentiality. tor August 25, 2005 August 25, 2005: 01 102245 remote 0.1.0.14 0.1.0.14

Tor is an implementation of second generation Onion Routing, a connection-oriented anonymizing communication service.

The Diffie-Hellman implementation of Tor fails to verify the cryptographic strength of keys which are used during handshakes.

By setting up a malicious Tor server and enticing users to use this server as first hop, a remote attacker could read and modify all traffic of the user.

There is no known workaround at this time.

All Tor users should upgrade to the latest version:
