Notes

[wheezy] - mysql-5.5 <postponed> (Wait for next upstream security/bugfix release)
https://www.openwall.com/lists/oss-security/2018/04/08/2
Result from an incomplete fix for CVE-2015-3152 and related CVE for
Oracle products.
For MariaDB: if one connects to the remote server using the embedded library
(libmysqld), then SSL is not enforced.
Fixed in MariaDB: 5.5.60, 10.0.35, 10.1.33, 10.2.15, and 10.3.7
https://github.com/MariaDB/server/commit/f5369faf5bbf
For Oracle: https://github.com/mysql/mysql-server/commit/bbc2e37fe4e
fixed in 5.5.61, 5.6.41, 5.7.23
Strictly speaking though the CVE would be only for Oracle MySQL, for practical
reasons still tracking as well MariaDB here.
