Changes in MySQL Connector/Python 2.1.4 (2016-10-06, General Availability)

Security Notes

  • The linked OpenSSL library for Connector/Python Commercial has been updated to version 1.0.1q. Issues fixed in the new OpenSSL version are described at

    This change does not affect Oracle-produced MySQL Community builds of Connector/Python, which use the yaSSL library instead. The change also does not affect connections made using any pure-Python implementation of Connector/Python, for which the version of OpenSSL used is whatever is installed on the system.

Bugs Fixed

  • Connector/Python failed to establish connections using the cleartext client-side authentication plugin for accounts using the PAM server-side authentication plugin. Thanks to Daniël van Eeden for the patch. (Bug #22873551, Bug #80609)

  • A potential SQL injection vector was eliminated. (Bug #22529828, Bug #24816150, Bug #19487642, Bug #73611)

  • Connections made using the C Extension failed when the ssl_ca parameter was given without ssl_cert and ssl_key. (Bug #21879914, Bug #79835, Bug #22494320)

  • For connections made with consume_results=True, consume_results was reset to False after callproc() execution failure. (Bug #21879859)

    References: This issue is a regression of: Bug #21492815.

  • In connections for which compress=True, LOAD DATA LOCAL statements produced Packets out of error errors. (Bug #21449996)

  • Attempts to insert Python ByteArray data into binary table columns failed.

    Update: this was fixed in the Python implementation of Connector/Python, but not in the c-extension until v8.0.29. (Bug #77822, Bug #21498719)
