CVE-2017-0375 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2016-9079 5 Debian, Microsoft, Mozilla and 2 more 12 Debian Linux, Windows, Firefox and 9 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox < 50.0.2, Firefox ESR < 45.5.1, and Thunderbird < 45.5.1.
CVE-2016-8860 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM 7.5 HIGH
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-2016-1254 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Leap and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Tor before 0.2.8.12 might allow remote attackers to cause a denial of service (client crash) via a crafted hidden service descriptor.
CVE-2015-2929 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2015-2928 1 Torproject 1 Tor 2024-11-21 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-2015-2689 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM 7.5 HIGH
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.
CVE-2015-2688 1 Torproject 1 Tor 2024-11-21 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-2014-5117 1 Torproject 1 Tor 2024-11-21 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-2013-7295 1 Torproject 1 Tor 2024-11-21 4.0 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-2012-5573 1 Torproject 1 Tor 2024-11-21 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-2012-4922 1 Torproject 1 Tor 2024-11-21 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 2024-11-21 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.
CVE-2012-2250 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM N/A
Tor before 0.2.3.24-rc allows remote attackers to cause a denial of service (assertion failure and daemon exit) by performing link protocol negotiation incorrectly.
CVE-2012-2249 1 Torproject 1 Tor 2024-11-21 5.0 MEDIUM N/A
Tor before 0.2.3.23-rc allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a renegotiation attempt that occurs after the initiation of the V3 link protocol.
