Torproject Tor vulnerabilities

CVE-2010-0383 [MEDIUM] CVE-2010-0383: Tor before 0 Tor before 0.2.1.22, and 0.2.2.x before 0.2.2.7-alpha, uses deprecated identity keys for certain directory authorities, which makes it easier for man-in-the-middle attackers to compromise the anonymity of traffic sources and destinations.

CVE-2010-0385 [MEDIUM] CVE-2010-0385: Tor before 0 Tor before 0.2.1.22, and 0.2.2.x before 0.2.2.7-alpha, when functioning as a bridge directory authority, allows remote attackers to obtain sensitive information about bridge identities and bridge descriptors via a dbg-stability.txt directory query.

CVE-2009-2426 [MEDIUM] CVE-2009-2426: The connection_edge_process_relay_cell_not_open function in src/or/relay 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 [MEDIUM] CVE-2009-2425: Tor before 0 Tor before 0.2.0.35 allows remote attackers to cause a denial of service (application crash) via a malformed router descriptor.

CVE-2009-0939 [CRITICAL] CVE-2009-0939: Tor before 0 Tor before 0.2.0.34 treats incomplete IPv4 addresses as valid, which has unknown impact and attack vectors related to "Spec conformance," as demonstrated using 192.168.0.

CVE-2009-0938 [MEDIUM] CVE-2009-0938: Unspecified vulnerability in Tor before 0 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-2009-0937 [MEDIUM] CVE-2009-0937: Unspecified vulnerability in Tor before 0 Unspecified vulnerability in Tor before 0.2.0.34 allows directory mirrors to cause a denial of service via unknown vectors.

CVE-2009-0936 [MEDIUM] CVE-2009-0936: Unspecified vulnerability in Tor before 0 Unspecified vulnerability in Tor before 0.2.0.34 allows attackers to cause a denial of service (infinite loop) via "corrupt votes."

CVE-2009-0414 [CRITICAL] CVE-2009-0414: Unspecified vulnerability in Tor before 0 Unspecified vulnerability in Tor before 0.2.0.33 has unspecified impact and remote attack vectors that trigger heap corruption.

CVE-2008-5398 [CRITICAL] CVE-2008-5398: Tor before 0 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 [HIGH] CVE-2008-5397: Tor before 0 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 [MEDIUM] CVE-2007-4174: Tor before 0 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-2007-4097 [MEDIUM] CVE-2007-4097: Tor before 0 Tor before 0.1.2.15 sends "destroy cells" containing the reason for tearing down a circuit, which allows remote attackers to obtain sensitive information, contrary to specifications.

CVE-2007-4096 [MEDIUM] CVE-2007-4096: Buffer overflow in Tor before 0 Buffer overflow in Tor before 0.1.2.15, when using BSD natd support, allows remote attackers to cause a denial of service via unspecified vectors.

CVE-2007-4098 [MEDIUM] CVE-2007-4098: Tor before 0 Tor before 0.1.2.15 does not properly distinguish "streamids from different exits," which might allow remote attackers with control over Tor routers to inject cells into arbitrary streams.

CVE-2007-4099 [MEDIUM] CVE-2007-4099: Tor before 0 Tor before 0.1.2.15 can select a guard node beyond the first listed never-before-connected-to guard node, which allows remote attackers with control of certain guard nodes to obtain sensitive information and possibly leverage further attacks.

CVE-2007-3165 [MEDIUM] CVE-2007-3165: Tor before 0 Tor before 0.1.2.14 can construct circuits in which an entry guard is in the same family as the exit node, which might compromise the anonymity of traffic sources and destinations by exposing traffic to inappropriate remote observers.

CVE-2006-4508 [MEDIUM] CVE-2006-4508: Unspecified vulnerability in (1) Tor 0 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 [HIGH] CVE-2006-3409: Integer overflow in Tor before 0 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-2006-3413 [MEDIUM] CVE-2006-3413: The privoxy configuration file in Tor before 0 The privoxy configuration file in Tor before 0.1.1.20, when run on Apple OS X, logs all data via the "logfile", which allows attackers to obtain potentially sensitive information.
