CVE-2017-8819 | 2 Debian, Tor Project | 2 Debian Linux, Tor | 2019-10-02 | 5.0 MEDIUM | 7.5 HIGH |
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, the replay-cache protection mechanism is ineffective for v2 onion services, aka TROVE-2017-009. An attacker can send many INTRODUCE2 cells to trigger this issue. | |||||
CVE-2017-8822 | 2 Debian, Tor Project | 2 Debian Linux, Tor | 2017-12-21 | 4.3 MEDIUM | 3.7 LOW |
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, relays (that have incompletely downloaded descriptors) can pick themselves in a circuit path, leading to a degradation of anonymity, aka TROVE-2017-012. | |||||
CVE-2017-8820 | 2 Debian, Tor Project | 2 Debian Linux, Tor | 2017-12-21 | 5.0 MEDIUM | 7.5 HIGH |

CVE-2017-8821 | 2 Debian, Tor Project | 2 Debian Linux, Tor | 2017-12-21 | 5.0 MEDIUM | 7.5 HIGH |
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, an attacker can cause a denial of service (application hang) via crafted PEM input that signifies a public key requiring a password, which triggers an attempt by the OpenSSL library to ask the user for the password, aka TROVE-2017-011. | |||||
CVE-2017-8823 | 2 Debian, Tor Project | 2 Debian Linux, Tor | 2017-12-21 | 6.8 MEDIUM | 8.1 HIGH |
In Tor before 0.2.5.16, 0.2.6 through 0.2.8 before 0.2.8.17, 0.2.9 before 0.2.9.14, 0.3.0 before 0.3.0.13, and 0.3.1 before 0.3.1.9, there is a use-after-free in onion service v2 during intro-point expiration because the expiring list is mismanaged in certain error cases, aka TROVE-2017-013. |
