|---|---|---|---|---|
| CVE-2023-23589 | 3 Debian, Fedoraproject, Torproject | 3 Debian Linux, Fedora, Tor | 2024-11-21 | 6.5 Medium |
| The SafeSocks option in Tor before 0.4.7.13 has a logic error in which the unsafe SOCKS4 protocol can be used but not the safe SOCKS4a protocol, aka TROVE-2022-002. | ||||
| CVE-2022-33903 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| Tor 0.4.7.x before 0.4.7.8 allows a denial of service via the wedging of RTT estimation. | ||||
| CVE-2021-46702 | 2 Microsoft, Torproject | 2 Windows, Tor | 2024-11-21 | 5.5 Medium |
| 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. | ||||
| CVE-2021-38385 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| Tor before 0.3.5.16, 0.4.5.10, and 0.4.6.7 mishandles the relationship between batch-signature verification and single-signature verification, leading to a remote assertion failure, aka TROVE-2021-007. | ||||
| CVE-2021-34550 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| An issue was discovered in Tor before 0.4.6.5, aka TROVE-2021-006. The v3 onion service descriptor parsing allows out-of-bounds memory access, and a client crash, via a crafted onion service descriptor | ||||
| CVE-2021-34549 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| An issue was discovered in Tor before 0.4.6.5, 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. | ||||
| CVE-2021-34548 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| An issue was discovered in Tor before 0.4.6.5, aka TROVE-2021-003. An attacker can forge RELAY_END or RELAY_RESOLVED to bypass the intended access control for ending a stream. | ||||
| CVE-2021-28090 | 2 Fedoraproject, Torproject | 2 Fedora, Tor | 2024-11-21 | 5.3 Medium |
| Tor before 0.4.5.7 allows a remote attacker to cause Tor directory authorities to exit with an assertion failure, aka TROVE-2021-002. | ||||
| CVE-2021-28089 | 2 Fedoraproject, Torproject | 2 Fedora, Tor | 2024-11-21 | 7.5 High |
| Tor before 0.4.5.7 allows a remote participant in the Tor directory protocol to exhaust CPU resources on a target, aka TROVE-2021-001. | ||||
| CVE-2020-8516 | 1 Torproject | 1 Tor | 2024-11-21 | 5.3 Medium |
| The daemon in Tor through 0.4.1.8 and 0.4.2.x through 0.4.2.6 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 | ||||
| CVE-2020-15572 | 1 Torproject | 1 Tor | 2024-11-21 | 7.5 High |
| Tor before 0.4.3.6 has an out-of-bounds memory access that allows a remote denial-of-service (crash) attack against Tor instances built to use Mozilla Network Security Services (NSS), aka TROVE-2020-001. | ||||
| CVE-2020-10593 | 2 Opensuse, Torproject | 3 Backports Sle, Leap, Tor | 2024-11-21 | 7.5 High |
| Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 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. | ||||
| CVE-2020-10592 | 2 Opensuse, Torproject | 3 Backports, Leap, Tor | 2024-11-21 | 7.5 High |
| Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (CPU consumption), aka TROVE-2020-002. | ||||
| CVE-2019-8955 | 1 Torproject | 1 Tor | 2024-11-21 | N/A |
| In Tor before 0.3.3.12, 0.3.4.x before 0.3.4.11, 0.3.5.x before 0.3.5.8, and 0.4.x before 0.4.0.2-alpha, remote denial of service against Tor clients and relays can occur via memory exhaustion in the KIST cell scheduler. | ||||
| CVE-2018-0491 | 1 Torproject | 1 Tor | 2024-11-21 | N/A |
| A use-after-free issue was discovered in Tor 0.3.2.x before 0.3.2.10. It allows remote attackers to cause a denial of service (relay crash) because the KIST implementation allows a channel to be added more than once in the pending list. | ||||
| CVE-2018-0490 | 2 Debian, Torproject | 2 Debian Linux, Tor | 2024-11-21 | N/A |
| An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting. | ||||
| CVE-2017-16541 | 5 Apple, Debian, Linux and 2 more | 11 Macos, Debian Linux, Linux Kernel and 8 more | 2024-11-21 | 6.5 Medium |
| 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. | ||||
| CVE-2017-0380 | 1 Torproject | 1 Tor | 2024-11-21 | N/A |
| The rend_service_intro_established function in or/rendservice.c in Tor before 0.2.8.15, 0.2.9.x before 0.2.9.12, 0.3.0.x before 0.3.0.11, 0.3.1.x before 0.3.1.7, and 0.3.2.x before 0.3.2.1-alpha, when SafeLogging is disabled, allows attackers to obtain sensitive information by leveraging access to the log files of a hidden service, because uninitialized stack data is included in an error message about construction of an introduction point circuit. | ||||
| CVE-2017-0377 | 1 Torproject | 1 Tor | 2024-11-21 | N/A |
| Tor 0.3.x before 0.3.0.9 has a guard-selection algorithm that only considers the exit relay (not the exit relay's family), which might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families. | ||||
| CVE-2017-0376 | 2 Debian, Torproject | 2 Debian Linux, Tor | 2024-11-21 | N/A |
| The hidden-service feature in Tor before 0.3.0.8 allows a denial of service (assertion failure and daemon exit) in the connection_edge_process_relay_cell function via a BEGIN_DIR cell on a rendezvous circuit. | ||||
