CVE-2017-10789 (opens in a new tab)How to fix?
Upgrade Ubuntu:16.04 libdbd-mysql-perl to version 4.033-1ubuntu0.1+esm1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libdbd-mysql-perl package and not the libdbd-mysql-perl package as distributed by Ubuntu.
See How to fix? for Ubuntu:16.04 relevant fixed versions and status.
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.
