OpenWall just published a security advisory entitled Passive Analysis of SSH (Secure Shell) Traffic. This advisory demonstrates several weaknesses in implementations of SSH (Secure Shell) protocols. When exploited, they let the attacker obtain sensitive information (basically password lengths) by passively monitoring encrypted SSH sessions. Fix information, patches to reduce the impact of traffic analysis, and a tool to demonstrate the attacks are provided.
