FreeBSD -- ssh-add does not honor per-hop destination constraints
Problem Description: When using ssh-add1 to add smartcard keys to ssh-agent1 with per-hop destination constraints, a logic error prevented the constraints from being sent to the agent resulting in keys being added to the agent without constraints. Impact: A malicious server could leverage the key...
