Tor 0.1.0.13 and earlier, and experimental versions 0.1.1.4-alpha and earlier, does not reject certain weak keys when using ephemeral Diffie-Hellman (DH) handshakes, which allows malicious Tor servers to obtain the keys that a client uses for other systems in the circuit.

Security readout for executives and security teams

This Tor flaw affects very old 2005-era clients. A malicious Tor server could exploit weak Diffie-Hellman handling to learn keys a client used elsewhere in the Tor circuit, creating confidentiality risk for users relying on those versions. Likely limited to legacy or archived Tor deployments running the named versions. Modern supported Tor installations are not identified as affected in the provided sources. Prioritize only if the organization still runs legacy Tor software or maintains old investigative, research, or archived environments. For current supported Tor deployments, the provided evidence does not show exposure. Mitigation focus: Inventory Tor clients and relays for the affected version ranges.; Remove or isolate Tor 0.1.0.13 and earlier installations.; Remove or isolate experimental 0.1.1.4-alpha and earlier builds..
