CVE-2006-3411 describes a vulnerability in Tor versions prior to 0.1.1.20 where TLS handshakes generated public-private keys based on the TLS context instead of the specific connection. This flaw made it easier for remote attackers to conduct brute-force attacks against the encryption keys, potentially compromising confidentiality and integrity.

There is no evidence of active exploitation, and no public exploit code or significant community discussion has been identified.
