Connector/ODBC 5.3 Commercial has been updated to use OpenSSL version 1.0.1g, which has been publicly reported as not vulnerable to CVE-2014-0160. Please see Oracle Note #1645479.1 for further details.
Since the only change in Connector/ODBC 5.3.3 is the inclusion of OpenSSL libraries publicly reported as unaffected by CVE-2014-0160, and since Oracle-produced MySQL Community builds use yaSSL libraries, which have been reported as not affected by CVE-2014-0160, Oracle will not produce builds for Connector/ODBC Community for version 5.3.3. This means the Community edition of Connector/ODBC will skip version 5.3.3. (Bug #18533200)
