1 CVE-2011-4897 200 +Info 2011-12-22 2011-12-30
4.3
None Remote Medium Not required Partial None None
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.
2 CVE-2011-4896 200 +Info 2011-12-22 2011-12-30
4.3
None Remote Medium Not required Partial None None
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.
3 CVE-2011-4895 200 +Info 2011-12-22 2011-12-23
4.3
None Remote Medium Not required Partial None None
Tor before 0.2.2.34, when configured as a bridge, sets up circuits through a process different from the process used by a client, which makes it easier for remote attackers to enumerate bridges by observing circuit building.
4 CVE-2011-4894 200 +Info 2011-12-22 2011-12-23
4.3
None Remote Medium Not required Partial None None
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.
5 CVE-2011-2778 119 DoS Exec Code Overflow Mem. Corr. 2011-12-22 2012-01-18
7.6
None Remote High Not required Complete Complete Complete
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.
6 CVE-2011-2769 200 +Info 2011-12-22 2012-01-18
4.3
None Remote Medium Not required Partial None None
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.
7 CVE-2011-2768 264 Bypass 2011-12-22 2012-01-18
5.8
None Remote Medium Not required Partial Partial None
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.

5.0
None Remote Low Not required None None Partial
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."
12 CVE-2011-0490 DoS 2011-01-19 2011-02-12
5.0
None Remote Low Not required None None Partial
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.

9.3
None Remote Medium Not required Complete Complete Complete
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.

5.0
None Remote Low Not required Partial None None
Tor before 0.1.1.20 uses OpenSSL pseudo-random bytes (RAND_pseudo_bytes) instead of cryptographically strong RAND_bytes, and seeds the entropy value at start-up with 160-bit chunks without reseeding, which makes it easier for attackers to conduct brute force guessing attacks.
23 CVE-2006-3418 2006-07-06 2008-09-05
5.0
None Remote Low Not required None Partial None
Tor before 0.1.1.20 does not validate that a server descriptor's fingerprint line matches its identity key, which allows remote attackers to spoof the fingerprint line, which might be trusted by users or other applications.
24 CVE-2006-3417 2006-07-06 2008-09-05
6.4
None Remote Low Not required Partial Partial None
Tor client before 0.1.1.20 prefers entry points based on is_fast or is_stable flags, which could allow remote attackers to be preferred over nodes that are identified as more trustworthy "entry guard" (is_guard) systems by directory authorities.
25 CVE-2006-3416 2006-07-06 2008-09-05
5.0
None Remote Low Not required None None Partial
** DISPUTED ** 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.

5.0
None Remote Low Not required Partial None None
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.
