[Bug 1067301] Re: ssh-add: Error reading response length from authentication socket.
This is a security bug as it is now, as if one uses agent forwarding, it is impossible to confirm the use of a certain key on a (possible compromized) machine.

Also, the linked debian bug is incorrect, as it is about using different key format; and this bug is about having the keyring interactively confirm each key signing request over the agent. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067301 Title: ssh-add: Error reading response length from authentication socket.
