CVE-2021-34549 | 1 Torproject | 1 Tor | 2024-11-21 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 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 | 4.3 MEDIUM | 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 | 5.0 MEDIUM | 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 | 7.8 HIGH | 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 | 5.0 MEDIUM | 7.5 HIGH |
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 | 5.0 MEDIUM | 7.5 HIGH |
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 | 5.0 MEDIUM | 7.5 HIGH |
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-2015-2929 | 1 Torproject | 1 Tor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
The Hidden Service (HS) client implementation in Tor before 0.2.4.27, 0.2.5.x before 0.2.5.12, and 0.2.6.x before 0.2.6.7 allows remote servers to cause a denial of service (assertion failure and application exit) via a malformed HS descriptor. | |||||
CVE-2015-2928 | 1 Torproject | 1 Tor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
The Hidden Service (HS) server implementation in Tor before 0.2.4.27, 0.2.5.x before 0.2.5.12, and 0.2.6.x before 0.2.6.7 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors. | |||||
CVE-2015-2689 | 1 Torproject | 1 Tor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle pending-connection resolve states during periods of high DNS load, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets. | |||||
CVE-2015-2688 | 1 Torproject | 1 Tor | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
buf_pullup in Tor before 0.2.4.26 and 0.2.5.x before 0.2.5.11 does not properly handle unexpected arrival times of buffers with invalid layouts, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via crafted packets. |
