Summary
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.

Severity ?
Summary
The rend_service_intro_established function in or/rendservice.c in Tor before 0.2.8.15, 0.2.9.x before 0.2.9.12, 0.3.0.x before 0.3.0.11, 0.3.1.x before 0.3.1.7, and 0.3.2.x before 0.3.2.1-alpha, when SafeLogging is disabled, allows attackers to obtain sensitive information by leveraging access to the log files of a hidden service, because uninitialized stack data is included in an error message about construction of an introduction point circuit.

Summary
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.

Summary
An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting.

Severity ?
Summary
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.

Summary
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.

Summary
Tor Browser 9.0.7 on Windows 10 build 10586 is vulnerable to information disclosure. This could allow local attackers to bypass the intended anonymity feature and obtain information regarding the onion services visited by a local user. This can be accomplished by analyzing RAM memory even several hours after the local user used the product. This occurs because the product doesn't properly free memory.

Severity ?
Summary
The daemon in Tor through 0.4.1.8 and 0.4.2.x through 0.4.2.6 does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information. NOTE: The network team of Tor claims this is an intended behavior and not a vulnerability

Summary
Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.

Vulnerability from fkie_nvd
Published
2014-07-30 16:55
Modified
2024-11-21 02:11
Severity ?
Summary
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.

Severity ?
Summary
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.

Severity ?
Summary
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.

Summary
A use-after-free issue was discovered in Tor 0.3.2.x before 0.3.2.10. It allows remote attackers to cause a denial of service (relay crash) because the KIST implementation allows a channel to be added more than once in the pending list.

Summary
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.

Summary
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.

Summary
The daemon in Tor through 0.4.1.8 and 0.4.2.x through 0.4.2.6 does not verify that a rendezvous node is known before attempting to connect to it, which might make it easier for remote attackers to discover circuit information. NOTE: The network team of Tor claims this is an intended behavior and not a vulnerability

Summary
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.

Summary
A use-after-free issue was discovered in Tor 0.3.2.x before 0.3.2.10. It allows remote attackers to cause a denial of service (relay crash) because the KIST implementation allows a channel to be added more than once in the pending list.

Summary
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.

Summary
The rend_service_intro_established function in or/rendservice.c in Tor before 0.2.8.15, 0.2.9.x before 0.2.9.12, 0.3.0.x before 0.3.0.11, 0.3.1.x before 0.3.1.7, and 0.3.2.x before 0.3.2.1-alpha, when SafeLogging is disabled, allows attackers to obtain sensitive information by leveraging access to the log files of a hidden service, because uninitialized stack data is included in an error message about construction of an introduction point circuit.

Summary
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.

Summary
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.

Summary
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.

Summary
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.

Summary
Tor before 0.3.5.10, 0.4.x before 0.4.1.9, and 0.4.2.x before 0.4.2.7 allows remote attackers to cause a Denial of Service (memory leak), aka TROVE-2020-004. This occurs in circpad_setup_machine_on_circ because a circuit-padding machine can be negotiated twice on the same circuit.

Summary
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.

Summary
Tor Browser 9.0.7 on Windows 10 build 10586 is vulnerable to information disclosure. This could allow local attackers to bypass the intended anonymity feature and obtain information regarding the onion services visited by a local user. This can be accomplished by analyzing RAM memory even several hours after the local user used the product. This occurs because the product doesn't properly free memory.

Summary
An issue was discovered in Tor before 0.2.9.15, 0.3.1.x before 0.3.1.10, and 0.3.2.x before 0.3.2.10. The directory-authority protocol-list subprotocol implementation allows remote attackers to cause a denial of service (NULL pointer dereference and directory-authority crash) via a misformatted relay descriptor that is mishandled during voting.

var-201401-0517
Vulnerability from variot
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. Tor (The Onion Router) is an implementation of the second generation onion routing, which is mainly used to access the Internet anonymously. There are security holes in Tor. An attacker could use this vulnerability to bypass security restrictions. There are vulnerabilities in Tor 0.2.4.19. Other versions may also be affected. This may aid in further attacks.
Update to version 0.2.4.22 solves these major and security problems:
-
Block authority signing keys that were used on authorities vulnerable to the heartbleed bug in OpenSSL (CVE-2014-0160).
-
Fix a memory leak that could occur if a microdescriptor parse fails during the tokenizing step.
-
The relay ciphersuite list is now generated automatically based on uniform criteria, and includes all OpenSSL ciphersuites with acceptable strength and forward secrecy.
-
Relays now trust themselves to have a better view than clients of which TLS ciphersuites are better than others.
-
Clients now try to advertise the same list of ciphersuites as Firefox 28.

"data": "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. Tor (The Onion Router) is an implementation of the second generation onion routing, which is mainly used to access the Internet anonymously. \nThere are security holes in Tor. An attacker could use this vulnerability to bypass security restrictions. There are vulnerabilities in Tor 0.2.4.19. Other versions may also be affected. This may aid in further attacks. \n \n Update to version 0.2.4.22 solves these major and security problems:\n \n - Block authority signing keys that were used on authorities vulnerable\n to the heartbleed bug in OpenSSL (CVE-2014-0160). \n \n - Fix a memory leak that could occur if a microdescriptor parse fails\n during the tokenizing step. \n \n - The relay ciphersuite list is now generated automatically based on\n uniform criteria, and includes all OpenSSL ciphersuites with acceptable\n strength and forward secrecy. \n \n - Relays now trust themselves to have a better view than clients of\n which TLS ciphersuites are better than others. \n \n - Clients now try to advertise the same list of ciphersuites as\n Firefox 28. \n \n For other changes see the upstream change log\n _______________________________________________________________________\n\n References:\n\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-7295\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0160\n http://advisories.mageia.org/MGASA-2014-0059.html\n http://advisories.mageia.org/MGASA-2014-0256.html\n _______________________________________________________________________\n\n Updated Packages:\n\n Mandriva Business Server 1/X86_64:\n 77035fd2ff3c6df5effbaf9ee78bdaf4 mbs1/x86_64/tor-0.2.4.22-1.mbs1.x86_64.rpm \n cccaec1a8425ebfce0bb7d8057d38d6e mbs1/SRPMS/tor-0.2.4.22-1.mbs1.src.rpm\n _______________________________________________________________________\n\n To upgrade automatically use MandrivaUpdate or urpmi.

Vulnerability from variot
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. Tor (The Onion Router) is an implementation of the second generation of onion routing, mainly used for anonymous access to the Internet. The application is prone to a remote denial-of-service vulnerability. Attackers may exploit this issue to cause an affected application to crash, resulting in a denial-of-service condition. Versions prior to Tor 0.2.4.4-alpha are vulnerable

var-201209-0412
Vulnerability from variot
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. Tor (The Onion Router) is an implementation of the second generation of onion routing, which allows users to communicate anonymously over the Internet. Tor has denial of service and security restrictions to bypass the vulnerability, which can allow an attacker to bypass certain security restrictions or cause a denial of service. Tor is prone to multiple denial-of-service vulnerabilities. Exploiting these issues can allow attackers to crash the affected computer, denying service to legitimate users. Versions prior to Tor 0.2.2.39 and 0.2.3.22-rc are vulnerable. The title and technical details have been changed to better reflect the underlying component affected. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Mandriva Linux Security Advisory MDVSA-2013:132 http://www.mandriva.com/en/support/security/
Package : tor Date : April 10, 2013 Affected: Business Server 1.0
Problem Description:
Updated tor package fixes security vulnerabilities:
Tor before 0.2.2.34, when configured as a client or bridge, sends a TLS certificate chain as part of an outgoing OR connection, which allows remote relays to bypass intended anonymity properties by reading this chain and then determining the set of entry guards that the client or bridge had selected (CVE-2011-2768).
Tor before 0.2.2.34, when configured as a bridge, accepts the CREATE and CREATE_FAST values in the Command field of a cell within an OR connection that it initiated, which allows remote relays to enumerate bridges by using these values (CVE-2011-2769).
routerlist.c in Tor before 0.2.2.38 uses a different amount of time for relay-list iteration depending on which relay is chosen, which might allow remote attackers to obtain sensitive information about relay selection via a timing side-channel attack (CVE-2012-3519).
Tor before 0.2.2.39, when waiting for a client to renegotiate, allowed it to add bytes to the input buffer, allowing a crash to be caused remotely (tor-5934, tor-6007).
The version of Tor shipped in MBS1 did not have correctly formed systemd unit and thus failed to start.
This updated version corrects this problem and restores working behaviour.

DESCRIPTION: Two vulnerabilities have been reported in Tor, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An assertion failure within the "tor_timegm()" function when handling time information within a directory object can be exploited to cause a crash.
2) An assertion failure within the "compare_tor_addr_to_addr_policy()" function when handling certain port values can be exploited to crash directory authorities.
SOLUTION: Update to version 0.2.2.39.
PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.

"data": "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. Tor (The Onion Router) is an implementation of the second generation of onion routing, which allows users to communicate anonymously over the Internet. Tor has denial of service and security restrictions to bypass the vulnerability, which can allow an attacker to bypass certain security restrictions or cause a denial of service. Tor is prone to multiple denial-of-service vulnerabilities. \nExploiting these issues can allow attackers to crash the affected computer, denying service to legitimate users. \nVersions prior to Tor 0.2.2.39 and 0.2.3.22-rc are vulnerable. The title and technical details have been changed to better reflect the underlying component affected. -----BEGIN PGP SIGNED MESSAGE-----\nHash: SHA1\n\n _______________________________________________________________________\n\n Mandriva Linux Security Advisory MDVSA-2013:132\n http://www.mandriva.com/en/support/security/\n _______________________________________________________________________\n\n Package : tor\n Date : April 10, 2013\n Affected: Business Server 1.0\n _______________________________________________________________________\n\n Problem Description:\n\n Updated tor package fixes security vulnerabilities:\n \n Tor before 0.2.2.34, when configured as a client or bridge, sends a TLS\n certificate chain as part of an outgoing OR connection, which allows\n remote relays to bypass intended anonymity properties by reading this\n chain and then determining the set of entry guards that the client\n or bridge had selected (CVE-2011-2768). \n \n Tor before 0.2.2.34, when configured as a bridge, accepts the CREATE\n and CREATE_FAST values in the Command field of a cell within an OR\n connection that it initiated, which allows remote relays to enumerate\n bridges by using these values (CVE-2011-2769). \n \n routerlist.c in Tor before 0.2.2.38 uses a different amount of time\n for relay-list iteration depending on which relay is chosen, which\n might allow remote attackers to obtain sensitive information about\n relay selection via a timing side-channel attack (CVE-2012-3519). \n \n Tor before 0.2.2.39, when waiting for a client to renegotiate, allowed\n it to add bytes to the input buffer, allowing a crash to be caused\n remotely (tor-5934, tor-6007). \n \n The version of Tor shipped in MBS1 did not have correctly formed\n systemd unit and thus failed to start. \n \n This updated version corrects this problem and restores working\n behaviour. \n _______________________________________________________________________\n\n References:\n\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2768\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2769\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3517\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3518\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-3519\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-4419\n http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2012-5573\n https://wiki.mageia.org/en/Support/Advisories/MGAA-2012-0184\n https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-0276\n https://wiki.mageia.org/en/Support/Advisories/MGASA-2012-0356\n _______________________________________________________________________\n\n Updated Packages:\n\n Mandriva Business Server 1/X86_64:\n 8cadc920e4452cd2a3551a3cb01d9fcf mbs1/x86_64/tor-0.2.2.39-1.mbs1.x86_64.rpm \n 7cbba7170bc4f9e6ee8409398437570c mbs1/SRPMS/tor-0.2.2.39-1.mbs1.src.rpm\n _______________________________________________________________________\n\n To upgrade automatically use MandrivaUpdate or urpmi.

var-201209-0470
Vulnerability from variot
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. Tor (The Onion Router) is an implementation of the second generation of onion routing, which allows users to communicate anonymously over the Internet. Tor is prone to multiple denial-of-service vulnerabilities. Exploiting these issues can allow attackers to crash the affected computer, denying service to legitimate users. Versions prior to Tor 0.2.2.39 and 0.2.3.22-rc are vulnerable. The title and technical details have been changed to better reflect the underlying component affected. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201301-03

"data": "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. Tor (The Onion Router) is an implementation of the second generation of onion routing, which allows users to communicate anonymously over the Internet. Tor is prone to multiple denial-of-service vulnerabilities. \nExploiting these issues can allow attackers to crash the affected computer, denying service to legitimate users. \nVersions prior to Tor 0.2.2.39 and 0.2.3.22-rc are vulnerable.

Vulnerability from variot
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. Tor (The Onion Router) is an implementation of the second generation of onion routing, mainly used for anonymous access to the Internet. A denial of service vulnerability exists in versions prior to Tor 0.2.3.23-rc that could allow a remote attacker to compromise an affected application. The application is prone to a remote denial-of-service vulnerability. Attackers may exploit this issue to cause an affected application to crash, resulting in a denial-of-service condition. Versions prior to Tor 0.2.4.4-alpha are vulnerable

"data": "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. Tor (The Onion Router) is an implementation of the second generation of onion routing, mainly used for anonymous access to the Internet. A denial of service vulnerability exists in versions prior to Tor 0.2.3.23-rc that could allow a remote attacker to compromise an affected application. The application is prone to a remote denial-of-service vulnerability. \nAttackers may exploit this issue to cause an affected application to crash, resulting in a denial-of-service condition. \nVersions prior to Tor 0.2.4.4-alpha are vulnerable",
