<impact type="normal">
|
|
<p>
|
|
When connecting to a server using the SSH2 protocol an attacker is able
|
|
to execute arbitrary code with the permissions of the user running
|
|
PuTTY by sending specially crafted packets to the client during the
|
|
authentication process but before host key verification.
|
|
</p>

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time. All users are encouraged to
|
|
upgrade to the latest available version of PuTTY.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All PuTTY users should upgrade to the latest version:
