Name of the Vulnerable Software and Affected Versions: Tor versions prior to 0.4.6.5 Description: The issue is related to errors in authorization, allowing a remote attacker to cause a denial of service. An attacker can forge RELAY END or RELAY RESOLVED to bypass the intended access control for...

CVE-2012-2249

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...

CVE-2012-3519

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-2011-4894

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-2011-2768

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...

CVE-2007-4099

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-2007-4098

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-2006-3419

Tor before 0.1.1.20 uses OpenSSL pseudo-random bytes RANDpseudobytes instead of cryptographically strong RANDbytes, 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...

CVE-2006-3413

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...

CVE-2006-3416

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...

CVE-2006-3418

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...

CVE-2006-3412

Tor before 0.1.1.20 does not sufficiently obey certain firewall options, which allows remote attackers to bypass intended access restrictions for dirservers, direct connections, or proxy servers...
