Description:
Roger Dingledine has reported a vulnerability in Tor, which potentially can be exploited by malicious people to disclose or modify certain sensitive information.
The vulnerability is caused due to the Tor client failing to reject certain weak keys when performing a Diffie-Hellman handshake. This can potentially be exploited by the first Tor server in the path to disclose all keys the client negotiates for the rest of the path and then read or modify all client traffic.
The vulnerability has been reported in versions 0.1.0.13 and prior.
