Vulnerability CVE-2006-3411 - CERT Civis.Net

Vulnerability Name:

CVE-2006-3411 (CCN-33071)

Assigned:

2006-05-23

Published:

2006-05-23

Updated:

2008-09-05

Summary:

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.
