Detailsinfo

A vulnerability, which was classified as critical, was found in Tor up to 0.1.1.19 (Network Encryption Software). Affected is an unknown part of the component Encryption Key. The manipulation with an unknown input leads to a missing encryption vulnerability. CWE is classifying the issue as CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. This is going to have an impact on confidentiality, and integrity. CVE summarizes:

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.

The weakness was presented 05/24/2006 (Website). The advisory is shared for download at secunia.com. This vulnerability is traded as CVE-2006-3411 since 07/06/2006. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

Upgrading to version 0.1.1.20 eliminates this vulnerability.
