An application using the MongoDB BI Connector ODBC Driver may encounter a memory-safety issue when a submitted SQL statement contains an unusually long run of digits following a LIMIT clause. The issue occurs only on connections where the driver's optional prefetch setting is enabled, and stems from the driver copying the digit sequence into a fixed-size internal buffer without checking its length. A user able to influence the numeric portion of a LIMIT clause could cause the hosting application process to terminate unexpectedly or corrupt adjacent memory in that process.
