|---|---|---|---|---|---|
| CVE-2020-8516 | 1 Torproject | 1 Tor | 2024-04-11 | 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.

| CVE-2021-46702 | 2 Microsoft, Torproject | 2 Windows, Tor | 2023-12-10 | 2.1 LOW | 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-2021-28090 | 2 Fedoraproject, Torproject | 2 Fedora, Tor | 2023-12-10 | 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-2020-10593 | 2 Opensuse, Torproject | 3 Backports Sle, Leap, Tor | 2023-12-10 | 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-2020-15572 | 1 Torproject | 1 Tor | 2023-12-10 | 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-2020-10592 | 2 Opensuse, Torproject | 3 Backports, Leap, Tor | 2023-12-10 | 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-2015-2928 | 1 Torproject | 1 Tor | 2023-12-10 | 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-2015-2688 | 1 Torproject | 1 Tor | 2023-12-10 | 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. | |||||

| CVE-2018-0491 | 1 Torproject | 1 Tor | 2023-12-10 | 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. | |||||
