MySQL Connector/ODBC Developer Guide
Connector/ODBC 5.3 is now built with MySQL client library 5.7.26, which includes OpenSSL 1.0.2R. Issues fixed in the new OpenSSL version are described at http://www.openssl.org/news/vulnerabilities.html. (Bug #29489006)
An exception was emitted when fetching contents of a BLOB/TEXT records after executing a statement as a server-side prepared statement with a bound parameter.
The workaround is not using parameters or specifying NO_SSPS=1 in the connection string; this allows the driver to fetch the data. (Bug #29282638, Bug #29512548, Bug #28790708, Bug #93895, Bug #94545, Bug #92078)
