Just changing the setting will only cause your database server to error
out on restart - you also need to create certificates and put them into
the server directory.
So whoever does this change must know what they are doing (to some extent).
Once SSL has been enabled, a cunning attacker may be able to steal
the server's private key (if I understood the vulnerability correctly)
and then launch man-in-the-middle attacks, i.e. impersonate the server,
to eavesdrop on encrypted communication.
The remedy would be to create a new key pair for the server.
