Hi!

There is a new vulnerability in MySQL client versions 5.5 and 5.6
which is related to SSL/TLS encryption and to older BACKRONYM
vulnerability.

As it is common, new vulnerability should have a name, logo and
website. So enjoy the *Riddle* at http://riddle.link/

Affected are only Oracle's MySQL clients in all versions 5.5 and 5.6
when SSL/TLS encryption is used. Verification of encryption
parameters and existence of SSL/TLS layer by MySQL client is done
*after* client successfully finish authentication.

For more details including mitigation, look at Technical section on
vulnerability website: http://riddle.link/

Just to note that also last version 6.0.2 of MySQL Connector/C 6.0 
series (which is still supported) is affected by this vulnerability.
