| CVE-2020-10593 | HIGH7.5 | 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. | 23/03/2020 |
| CVE-2020-10592 | HIGH7.5 | 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. | 23/03/2020 |
| CVE-2020-8516 | MEDIUM5.3 | 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 | 02/02/2020 |
| CVE-2015-2929 | HIGH7.5 | 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. | 24/01/2020 |
| CVE-2015-2928 | HIGH7.5 | 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. | 24/01/2020 |
| CVE-2015-2689 | HIGH7.5 | 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. | 24/01/2020 |
| CVE-2015-2688 | HIGH7.5 | 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. | 24/01/2020 |
| CVE-2019-13075 | MEDIUM5.3 | 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 befor | 30/06/2019 |
| CVE-2019-12383 | MEDIUM4.3 | 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. | 28/05/2019 |
| CVE-2019-8955 | HIGH7.5 | 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. | 21/02/2019 |
| CVE-2017-16639 | MEDIUM4.3 | Tor Browser on Windows before 8.0 allows remote attackers to bypass the intended anonymity feature and discover a client IP address, a different vulnerability than CVE-2017-16541. User interaction is required to trigger this vulnerability. | 14/09/2018 |
| CVE-2018-16983 | CRITICAL9.8 | 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. | 13/09/2018 |
| CVE-2018-0491 | HIGH7.5 | 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. | 05/03/2018 |
| CVE-2018-0490 | HIGH7.5 | 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 | 05/03/2018 |
| CVE-2016-1254 | HIGH7.5 | Tor before 0.2.8.12 might allow remote attackers to cause a denial of service (client crash) via a crafted hidden service descriptor. | 05/12/2017 |
| CVE-2017-16541 | MEDIUM6.5 | 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. | 04/11/2017 |
