| CVE-2012-5573 | 1 Torproject | 1 Tor | 2017-08-29 | 5.0 MEDIUM | N/A |
| The connection_edge_process_relay_cell function in or/relay.c in Tor before 0.2.3.25 maintains circuits even if an unexpected SENDME cell arrives, which might allow remote attackers to cause a denial of service (memory consumption or excessive cell reception rate) or bypass intended flow-control restrictions via a RELAY_COMMAND_SENDME command. | |||||
| CVE-2017-0377 | 1 Torproject | 1 Tor | 2017-07-14 | 5.0 MEDIUM | 7.5 HIGH |
| Tor 0.3.x before 0.3.0.9 has a guard-selection algorithm that only considers the exit relay (not the exit relay's family), which might allow remote attackers to defeat intended anonymity properties by leveraging the existence of large families. | |||||

| Tor before 0.2.8.9 and 0.2.9.x before 0.2.9.4-alpha had internal functions that were entitled to expect that buf_t data had NUL termination, but the implementation of or/buffers.c did not ensure that NUL termination was present, which allows remote attackers to cause a denial of service (client, hidden service, relay, or authority crash) via crafted data. | |||||
| CVE-2014-5117 | 1 Torproject | 1 Tor | 2017-01-07 | 5.8 MEDIUM | N/A |
| Tor before 0.2.4.23 and 0.2.5 before 0.2.5.6-alpha maintains a circuit after an inbound RELAY_EARLY cell is received by a client, which makes it easier for remote attackers to conduct traffic-confirmation attacks by using the pattern of RELAY and RELAY_EARLY cells as a means of communicating information about hidden service names. | |||||
| CVE-2012-2250 | 1 Torproject | 1 Tor | 2014-02-21 | 5.0 MEDIUM | N/A |

| Tor before 0.2.4.20, when OpenSSL 1.x is used in conjunction with a certain HardwareAccel setting on Intel Sandy Bridge and Ivy Bridge platforms, does not properly generate random numbers for (1) relay identity keys and (2) hidden-service identity keys, which might make it easier for remote attackers to bypass cryptographic protection mechanisms via unspecified vectors. | |||||
| CVE-2012-4922 | 1 Torproject | 1 Tor | 2013-08-22 | 5.0 MEDIUM | N/A |
| The tor_timegm function in common/util.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.22-rc, does not properly validate time values, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a malformed directory object, a different vulnerability than CVE-2012-4419. | |||||
| CVE-2012-4419 | 1 Torproject | 1 Tor | 2013-08-22 | 5.0 MEDIUM | N/A |
| The compare_tor_addr_to_addr_policy function in or/policies.c in Tor before 0.2.2.39, and 0.2.3.x before 0.2.3.21-rc, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a zero-valued port field that is not properly handled during policy comparison. | |||||
