CVE-2006-3416 1 Tor 1 Tor 2024-08-07 5.0 MEDIUM N/A
Tor before 0.1.1.20 kills the circuit when it receives an unrecognized relay command, which causes network circuits to be disbanded. NOTE: while this item is listed under the "Security fixes" section of the developer changelog, the developer clarified on 20060707 that this is only a self-DoS. Therefore this issue should not be included in CVE
CVE-2012-3519 1 Tor 1 Tor 2024-02-28 5.0 MEDIUM N/A
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-2012-3517 1 Tor 1 Tor 2024-02-28 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.
CVE-2012-3518 1 Tor 1 Tor 2024-02-28 5.0 MEDIUM N/A
The networkstatus_parse_vote_from_string function in routerparse.c in Tor before 0.2.2.38 does not properly handle an invalid flavor name, which allows remote attackers to cause a denial of service (out-of-bounds read and daemon crash) via a crafted (1) vote document or (2) consensus document.
CVE-2011-1924 1 Tor 1 Tor 2024-02-28 5.0 MEDIUM N/A
Buffer overflow in the policy_summarize function in or/policies.c in Tor before 0.2.1.30 allows remote attackers to cause a denial of service (directory authority crash) via a crafted policy that triggers creation of a long port list.
CVE-2011-4894 1 Tor 1 Tor 2024-02-28 4.3 MEDIUM N/A
Tor before 0.2.2.34, when configured as a bridge, uses direct DirPort access instead of a Tor TLS connection for a directory fetch, which makes it easier for remote attackers to enumerate bridges by observing DirPort connections.
CVE-2011-0427 1 Tor 1 Tor 2024-02-28 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-2011-0492 1 Tor 1 Tor 2024-02-28 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-2010-0384 1 Tor 1 Tor 2024-02-28 2.1 LOW N/A
Tor 0.2.2.x before 0.2.2.7-alpha, when functioning as a directory mirror, does not prevent logging of the client IP address upon detection of erroneous client behavior, which might make it easier for local users to discover the identities of clients in opportunistic circumstances by reading log files.
CVE-2011-2769 1 Tor 1 Tor 2024-02-28 4.3 MEDIUM N/A
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-2010-0385 1 Tor 1 Tor 2024-02-28 5.0 MEDIUM N/A
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-2010-1676 1 Tor 1 Tor 2024-02-28 10.0 HIGH N/A
Heap-based buffer overflow in Tor before 0.2.1.28 and 0.2.2.x before 0.2.2.20-alpha allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via unspecified vectors.
CVE-2011-4896 1 Tor 1 Tor 2024-02-28 4.3 MEDIUM N/A
Tor before 0.2.2.24-alpha continues to use a reachable bridge that was previously configured but is not currently configured, which might allow remote attackers to obtain sensitive information about clients in opportunistic circumstances by monitoring network traffic to the bridge port.
CVE-2011-4897 1 Tor 1 Tor 2024-02-28 4.3 MEDIUM N/A
Tor before 0.2.2.25-alpha, when configured as a relay without the Nickname configuration option, uses the local hostname as the Nickname value, which allows remote attackers to obtain potentially sensitive information by reading this value.
CVE-2011-0016 1 Tor 1 Tor 2024-02-28 2.1 LOW N/A
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not properly manage key data in memory, which might allow local users to obtain sensitive information by leveraging the ability to read memory that was previously used by a different process.
CVE-2011-2768 1 Tor 1 Tor 2024-02-28 5.8 MEDIUM N/A
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-2011-0490 1 Tor 1 Tor 2024-02-28 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-2011-2778 1 Tor 1 Tor 2024-02-28 7.6 HIGH N/A
Multiple heap-based buffer overflows in Tor before 0.2.2.35 allow remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by (1) establishing a SOCKS connection to SocksPort or (2) leveraging a SOCKS proxy configuration.
CVE-2010-0383 1 Tor 1 Tor 2024-02-28 5.0 MEDIUM N/A
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-2011-0491 1 Tor 1 Tor 2024-02-28 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."
