| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2017-06-09 | CVE-2017-0376 | Reachable Assertion vulnerability in multiple products The hidden-service feature in Tor before 0.3.0.8 allows a denial of service (assertion failure and daemon exit) in the connection_edge_process_relay_cell function via a BEGIN_DIR cell on a rendezvous circuit. | 5.0 |
| 2017-06-09 | CVE-2017-0375 | Reachable Assertion vulnerability in Torproject TOR The hidden-service feature in Tor before 0.3.0.8 allows a denial of service (assertion failure and daemon exit) in the relay_send_end_cell_from_edge_ function via a malformed BEGIN cell. | 5.0 |
| 2017-01-04 | CVE-2016-8860 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Torproject TOR 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. | 5.0 |
| 2014-07-30 | CVE-2014-5117 | RELAY_EARLY Security vulnerability in Tor 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. network torproject | 5.8 |
| 2014-01-17 | CVE-2013-7295 | Cryptographic Issues vulnerability in Torproject TOR 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. | 4.0 |
| 2013-01-01 | CVE-2012-5573 | Resource Management Errors vulnerability in Torproject TOR 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. | 5.0 |
| 2012-09-14 | CVE-2012-4922 | Improper Input Validation vulnerability in Torproject TOR 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. | 5.0 |
| 2012-09-14 | CVE-2012-4419 | Unspecified vulnerability in Torproject TOR 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. | 5.0 |
