Summary

The MongoDB BI Connector ODBC Driver may write outside the bounds of a fixed-size buffer when an application supplies an unusually long catalog, schema, or object name to a metadata retrieval function. This may result in memory corruption within the calling application's process, leading to abnormal termination and, under certain conditions, the potential for arbitrary code execution.
