The remote SSH host key has been generated on a Debian
or Ubuntu system which contains a bug in the random number
generator of its OpenSSL library.

An attacker can easily obtain the private part of the remote
key and use this to set up decipher the remote session or
set up a man in the middle attack.

Consider all cryptographic material generated on the remote host
to be guessable. In particuliar, all SSH, SSL and OpenVPN key
material should be re-generated.
