CVE-2017-10789 not yet assigned priority: Debian including 1 source packages (libdbd-mysql-perl), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
