Tor clients can completely loose anonymity, confidentiality, and data
integrity if the first Tor server in their path is malicious.
Specifically, if the Tor client chooses a malicious Tor server for her
first hop in the circuit, that server can learn all the keys she
negotiates for the rest of the circuit (or just spoof the whole
circuit), and then read and/or modify all her traffic over that
circuit."

(Tor: Information disclosure)

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

    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.
  
Workaround :

    There is no known workaround at this time."
