Tor allows remote attackers to discover the IP address of a hidden service by accessing this service at a high rate, thereby changing the server's CPU temperature and consequently changing the pattern of time values visible through (1) ICMP timestamps, (2) TCP sequence numbers, and (3) TCP timestamps, a different vulnerability than CVE-2006-0414. NOTE: it could be argued that this is a laws-of-physics vulnerability that is a fundamental design limitation of certain hardware implementations, so perhaps this issue should not be included in CVE.

Security readout for executives and security teams

This CVE describes a deanonymization weakness against Tor hidden services. An attacker could infer the hidden service server's real IP address by causing workload changes and observing timing-related clock-skew signals. The source notes this may reflect hardware physics limits rather than a conventional software bug. Exposure is most relevant to organizations operating Tor hidden services, especially older deployments or hosts exposing network timestamp behavior. The source bundle does not identify affected Tor versions, operating systems, hardware, or current applicability. Treat this as a privacy and operational-security concern, not a routine patch ticket. Prioritize review if the business depends on Tor hidden services or anonymity of infrastructure location. Mitigation focus: Check current Tor Project guidance for hidden-service deanonymization mitigations.; Inventory any Tor hidden services and their hosting environments.; Disable unnecessary externally observable timestamp services where supported..
