Summary

Fixes buffer Overflow for Large Connection String Key Values

Description

  • Changes the allocation from stack to heap for parsing in values into the DataSource
  • Also includes changes for allowing larger values to be read from the ODBC Data Source GUI
  • Prior to changes, key-value pairs which contain values with length over 1024 will crash the application on a buffer overflow.
