Medium 6.5
NoSQL command injection via mismatched raw BSON length prefix written verbatim to the wire
A data-validation flaw exists in the BSON handling and binary serialization path of the MongoDB C# Driver. When an application constructs a raw or lazy BSON document object from externally supplied binary data, the driver does not verify that the size quantit…

Heap overflow via 32-bit length wrap of the URI username in Windows Kerberos auth message wrapping
A 32-bit integer wraparound in the MongoDB C Driver's Windows-only Kerberos/SSPI authentication code can cause an undersized heap buffer to be allocated when an excessively long credential value is supplied in the client's connection configuration. A party ab…

Memory-exhaustion denial of service via unbounded symbol interning during BSON/JSON deserialization
The MongoDB C# Driver's BSON library contains an uncontrolled resource consumption weakness in its deserialization handling of one BSON value type. An application that deserializes untrusted content with the library retains data derived from that content for …
