CVE-2017-10789: Dbd-MySQL Project Dbd-MySQL

Medium severity, CVSS 5.9. EPSS: 2.2% chance of exploitation in the next 30 days.

The DBD::mysql module through 4.043 for Perl uses the mysql_ssl=1 setting to mean that SSL is optional (even though this setting's documentation has a "your communication with the server will be encrypted" statement), which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, a related issue to CVE-2015-3152.
