CVE-2011-0491 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
The tor_realloc function in Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not validate a certain size value during memory allocation, which might allow remote attackers to cause a denial of service (daemon crash) via unspecified vectors, related to "underflow errors."
CVE-2011-0427 1 Tor 1 Tor 2017-08-16 6.8 MEDIUM N/A
Heap-based buffer overflow in Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.
CVE-2011-0490 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha makes calls to Libevent within Libevent log handlers, which might allow remote attackers to cause a denial of service (daemon crash) via vectors that trigger certain log messages.
CVE-2011-0492 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha allows remote attackers to cause a denial of service (assertion failure and daemon exit) via blobs that trigger a certain file size, as demonstrated by the cached-descriptors.new file.
CVE-2011-0493 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha might allow remote attackers to cause a denial of service (assertion failure and daemon exit) via vectors related to malformed router caches and improper handling of integer values.
CVE-2009-2426 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
The connection_edge_process_relay_cell_not_open function in src/or/relay.c in Tor 0.2.x before 0.2.0.35 and 0.1.x before 0.1.2.8-beta allows exit relays to have an unspecified impact by causing controllers to accept DNS responses that redirect to an internal IP address via unknown vectors. NOTE: some of these details are obtained from third party information.
CVE-2009-2425 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
Tor before 0.2.0.35 allows remote attackers to cause a denial of service (application crash) via a malformed router descriptor.
CVE-2009-0938 1 Tor 1 Tor 2017-08-16 5.0 MEDIUM N/A
Unspecified vulnerability in Tor before 0.2.0.34 allows directory mirrors to cause a denial of service (exit node crash) via "malformed input."
CVE-2008-5398 1 Tor 1 Tor 2017-08-07 9.3 HIGH N/A
Tor before 0.2.0.32 does not properly process the ClientDNSRejectInternalAddresses configuration option in situations where an exit relay issues a policy-based refusal of a stream, which allows remote exit relays to have an unknown impact by mapping an internal IP address to the destination hostname of a refused stream.
CVE-2008-5397 1 Tor 1 Tor 2017-08-07 7.2 HIGH N/A
Tor before 0.2.0.32 does not properly process the (1) User and (2) Group configuration options, which might allow local users to gain privileges by leveraging unintended supplementary group memberships of the Tor process.
CVE-2007-4174 1 Tor 1 Tor 2017-07-28 5.8 MEDIUM N/A
Tor before 0.1.2.16, when ControlPort is enabled, does not properly restrict commands to localhost port 9051, which allows remote attackers to modify the torrc configuration file, compromise anonymity, and have other unspecified impact via HTTP POST data containing commands without valid authentication, as demonstrated by an HTML form (1) hosted on a web site or (2) injected by a Tor exit node.
CVE-2006-4508 2 Scatterchat, Tor 2 Scatterchat, Tor 2017-07-19 4.0 MEDIUM N/A
Unspecified vulnerability in (1) Tor 0.1.0.x before 0.1.0.18 and 0.1.1.x before 0.1.1.23, and (2) ScatterChat before 1.0.2, allows remote attackers operating a Tor entry node to route arbitrary Tor traffic through clients or cause a denial of service (flood) via unspecified vectors.
CVE-2006-3409 1 Tor 1 Tor 2017-07-19 7.5 HIGH N/A
Integer overflow in Tor before 0.1.1.20 allows remote attackers to execute arbitrary code via crafted large inputs, which result in a buffer overflow when elements are added to smartlists.
CVE-2006-3408 1 Tor 1 Tor 2017-07-19 5.0 MEDIUM N/A
Unspecified vulnerability in the directory server (dirserver) in Tor before 0.1.1.20 allows remote attackers to cause an unspecified denial of service via unknown vectors.
CVE-2006-3407 1 Tor 1 Tor 2017-07-19 6.4 MEDIUM N/A
Tor before 0.1.1.20 allows remote attackers to spoof log entries or possibly execute shell code via strings with non-printable characters.
CVE-2006-3410 1 Tor 1 Tor 2017-07-19 5.0 MEDIUM N/A
Tor before 0.1.1.20 creates "internal circuits" primarily consisting of nodes with "useful exit nodes," which allows remote attackers to conduct unspecified statistical attacks.
CVE-2006-0414 1 Tor 1 Tor 2017-07-19 5.0 MEDIUM N/A
Tor before 0.1.1.20 allows remote attackers to identify hidden services via a malicious Tor server that attempts a large number of accesses of the hidden service, which eventually causes a circuit to be built through the malicious server.
CVE-2005-2050 1 Tor 1 Tor 2017-07-10 5.0 MEDIUM N/A
Unknown vulnerability in Tor before 0.1.0.10 allows remote attackers to read arbitrary memory and possibly key information from the exit server's process space.
CVE-2005-2643 1 Tor 1 Tor 2016-10-17 5.0 MEDIUM N/A
Tor 0.1.0.13 and earlier, and experimental versions 0.1.1.4-alpha and earlier, does not reject certain weak keys when using ephemeral Diffie-Hellman (DH) handshakes, which allows malicious Tor servers to obtain the keys that a client uses for other systems in the circuit.
CVE-2012-3517 1 Tor 1 Tor 2013-08-21 5.0 MEDIUM N/A
Use-after-free vulnerability in dns.c in Tor before 0.2.2.38 might allow remote attackers to cause a denial of service (daemon crash) via vectors related to failed DNS requests.
