If you cannot patch yet, users should avoid opening the setup dialog for data sources with over-length file path settings to prevent triggering the vulnerability.
Description
A vulnerability in the MongoDB BI Connector ODBC Driver setup dialog can occur when a data source definition contains an over-length file path setting. This causes the dialog to write outside the bounds of an allocated buffer due to incorrect buffer capacity calculation during file or folder selection. The issue is triggered only when a user opens the setup dialog and initiates a file or folder selection for such a data source. The impact ranges from abnormal process termination to potential execution of unintended code under certain conditions.
