This is a Stable (GA) release of MariaDB Connector/ODBC 3.1.

MariaDB Connector/ODBC 3.1.23 is built on top of MariaDB Connector/C v.3.3.19.

Important Changes

• ODBC-494 - Incorrect string escaping in case of multibyte charsets. This could permit SQL injection in case of client side statement preparing(default for SQLExecDirect). The problematic character sets are big5, gbk, sjis, cp932

Bug Fixes

• ODBC-490 - SQLSpecialColumns with iOdbc on MacOS on ARM

• ODBC-496 - Small negative scale for SQL_C_NUMERIC parameter could cause buffer overflow

• ODBC-489 - UndefinedBehaviorSanitizer: nullptr-with-nonzero-offset /source/driver/ma_statement.cpp:2295:5

• ODBC-493 - Make LOCAL_INFILE_MODE_AUTO default for the connector - this is enables by default safer mode for LOCAL INFILE commands

• ODBC-492 - Wrong COLUMN_SIZE reported for datetime columns

• ODBC-495 - SQLGetTypeInfo does not return MAXIMUM_SCALE for temporal types with possible fractional part

• ODBC-475 - MariaDB ODBC Driver returns "Invalid information type" when asked for SQL_POSITIONED_STATEMENTS.

• ODBC-479 - Using SQLGetData with column > column count could crash the connector.

• ODBC-480 - Incorrect work of the SQLDescribeCol - it did not return column length if buffer parameter and buffer length were 0.
