2020-03-23 CVE-2020-10593 Tor before, 0.4.x before, and 0.4.2.x before allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit. Backports_sle, Leap, Tor 7.5
2023-01-14 CVE-2023-23589 The SafeSocks option in Tor before has a logic error in which the unsafe SOCKS4 protocol can be used but not the safe SOCKS4a protocol, aka TROVE-2022-002. Debian_linux, Fedora, Tor 6.5
2022-07-17 CVE-2022-33903 Tor 0.4.7.x before allows a denial of service via the wedging of RTT estimation. Tor 7.5
2021-06-29 CVE-2021-34549 An issue was discovered in Tor before, aka TROVE-2021-005. Hashing is mishandled for certain retrieval of circuit data. Consequently. an attacker can trigger the use of an attacker-chosen circuit ID to cause algorithm inefficiency. Tor 7.5
2021-03-19 CVE-2021-28089 Tor before allows a remote participant in the Tor directory protocol to exhaust CPU resources on a target, aka TROVE-2021-001. Fedora, Tor 7.5
2021-03-19 CVE-2021-28090 Tor before allows a remote attacker to cause Tor directory authorities to exit with an assertion failure, aka TROVE-2021-002. Fedora, Tor 5.3
2017-11-04 CVE-2017-16541 Tor Browser before 7.0.9 on macOS and Linux allows remote attackers to bypass the intended anonymity feature and discover a client IP address via vectors involving a crafted web site that leverages file:// mishandling in Firefox, aka TorMoil. NOTE: Tails is unaffected. Debian_linux, Enterprise_linux_desktop, Enterprise_linux_eus, Enterprise_linux_server, Enterprise_linux_server_aus, Enterprise_linux_server_tus, Enterprise_linux_workstation, Tor 6.5
2020-02-02 CVE-2020-8516 ** DISPUTED ** The daemon in Tor through and 0.4.2.x through does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information. NOTE: The network team of Tor claims this is an intended behavior and not a vulnerability. Tor 5.3
2022-02-26 CVE-2021-46702 Tor Browser 9.0.7 on Windows 10 build 10586 is vulnerable to information disclosure. This could allow local attackers to bypass the intended anonymity feature and obtain information regarding the onion services visited by a local user. This can be accomplished by analyzing RAM memory even several hours after the local user used the product. This occurs because the product doesn't properly free memory. Tor 5.5
2020-03-23 CVE-2020-10592 Tor before, 0.4.x before, and 0.4.2.x before allows remote attackers to cause a Denial of Service (CPU consumption), aka TROVE-2020-002. Backports, Leap, Tor 7.5
