<impact type="normal">
|
||
|
<p>A remote attacker, able to access the socket of the forwarding agent,
|
||
|
might be able to execute arbitrary code with the privileges of the

||
|
process or cause a Denial of Service condition.
|
||
|
Furthermore, a remote attacker might conduct a man-in-the-middle attack
|
||
|
targeting initial connection attempts where no host key for the server
|
||
|
has been cached by client yet.
