The remote FreeBSD host is missing a security-related update.
Simon Tatham reports :
This [0.63] release fixes multiple security holes in previous versions
of PuTTY, which can allow an SSH-2 server to make PuTTY overrun or
underrun buffers and crash. [...]
These vulnerabilities can be triggered before host key verification,
which means that you are not even safe if you trust the server you
think you're connecting to, since it could be spoofed over the network
and the host key check would not detect this before the attack could
Additionally, when PuTTY authenticated with a user's private key, the
private key or information equivalent to it was accidentally kept in
PuTTY's memory for the rest of its run, where it could be retrieved by
other processes reading PuTTY's memory, or written out to swap files
or crash dumps. This release fixes that as well.
