CVE-2011-4896

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...

Design/Logic Flaw

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-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...

Heap overflow

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-2011-2778

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...

Design/Logic Flaw

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...

Command injection

Tor before 0.2.2.34, when configured as a bridge, accepts the CREATE and CREATEFAST 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-2011-4895

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...

CVE-2011-2769

Tor before 0.2.2.34, when configured as a bridge, accepts the CREATE and CREATEFAST 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-2011-4896

Technical details (affected products, versions, root cause, fixes) are not provided in the connected documents. The CVE description remains the only published detail. Monitor for official updates.

CVE-2011-4894

CVE-2011-4894 affects Tor prior to 0.2.2.34 when run as a bridge. The issue is that DirPort connections are used directly for directory fetches instead of a Tor TLS connection, which can enable remote observers to enumerate bridges by monitoring DirPort activity. The available connected documents...

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-2011-4897

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-2011-2768

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-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

CVE-2011-2768 affects Tor before 0.2.2.34 when configured as a client or bridge. The vulnerability arises because Tor may send a TLS certificate chain as part of an outgoing OR connection, enabling remote relays to read the chain and infer the client’s entry guard set, thereby compromising anonym...
