Description

A vulnerability was found in openssh. This issue occurs when adding smartcard keys to ssh-agent(1) with per-hop destination constraints. A logic error prevented the constraints from being communicated to the agent, resulting in the keys being added without constraints. The common cases of non-smartcard keys and keys without destination constraints are unaffected.
