Description

Improper validation of a BSON array length in the MongoDB Go Driver can cause an out-of-bounds index and runtime panic when an application calls bson.RawArray.Validate or bsoncore.Array.Validate on a malformed four-byte array. An unauthenticated actor who can supply raw BSON array data to an affected application may terminate an unprotected application process, causing a denial of service. No confidentiality or integrity impact has been identified.
