/** Passing arbitrary connection string to ODBC Driver Manager is insecure, for the following reasons:
|
|
* 1. Driver Manager like unixODBC has multiple bugs like buffer overflow.
|
|
* 2. Driver Manager can interpret some parameters as a path to library for dlopen or a file to read,
|
|
* thus allows arbitrary remote code execution.
|
|
*
|
|
* This function will throw exception if connection string has insecure parameters.
|
|
* It may also modify connection string to harden it.
|
|
*
|
|
* Note that it is intended for ANSI (not multibyte) variant of connection string.
