Tor ≫ Tor

Tor allows remote attackers to discover the IP address of a hidden service by accessing this service at a high rate, thereby changing the server's CPU temperature and consequently changing the pattern of time values visible through (1) ICMP timestamp...

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...

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 bru...

Tor before 0.1.1.20 allows remote attackers to spoof log entries or possibly execute shell code via strings with non-printable characters.

Unspecified vulnerability in the directory server (dirserver) in Tor before 0.1.1.20 allows remote attackers to cause an unspecified denial of service via unknown vectors.

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.

Tor before 0.1.1.20 creates "internal circuits" primarily consisting of nodes with "useful exit nodes," which allows remote attackers to conduct unspecified statistical attacks.

TLS handshakes in Tor before 0.1.1.20 generate public-private keys based on TLS context rather than the connection, which makes it easier for remote attackers to conduct brute force attacks on the encryption keys.

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.

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.
