Title
MongoDB BI Connector Improper Memory Handling During Failed Kerberos Authentication May Cause Process Termination
Summary
An unauthenticated client that can reach a MongoDB Connector for BI deployment configured with Kerberos authentication may cause mongosqld to terminate when a crafted authentication exchange encounters a specific GSSAPI error-handling condition. This can interrupt BI Connector availability until the process restarts.
