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-2021-39246 4 Apple, Linux, Microsoft and 1 more 4 Macos, Linux Kernel, Windows and 1 more 2024-11-21 6.1 Medium
Tor Browser through 10.5.6 and 11.x through 11.0a4 allows a correlation attack that can compromise the privacy of visits to v2 onion addresses. Exact timestamps of these onion-service visits are logged locally, and an attacker might be able to compare them to timestamp data collected by the destination server (or collected by a rogue site within the Tor network).
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-2019-13075 1 Torproject 1 Tor Browser 2024-11-21 N/A
Tor Browser through 8.5.3 has an information exposure vulnerability. It allows remote attackers to detect the browser's language via vectors involving an IFRAME element, because text in that language is included in the title attribute of a LINK element for a non-HTML page. This is related to a behavior of Firefox before 68.
CVE-2019-12383 1 Torproject 1 Tor Browser 2024-11-21 4.3 Medium
Tor Browser before 8.0.1 has an information exposure vulnerability. It allows remote attackers to detect the browser's UI locale by measuring a button width, even if the user has a "Don't send my language" setting.
CVE-2018-16983 2 Noscript, Torproject 2 Noscript, Tor Browser 2024-11-21 N/A
NoScript Classic before 5.1.8.7, as used in Tor Browser 7.x and other products, allows attackers to bypass script blocking via the text/html;/json Content-Type value.
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.
