Description TEJ RATHI 2023-07-13 18:08:16 UTC 
Missing type validation in Samba's mdssvc RPC service for Spotlight can be used by an unauthenticated attacker to trigger
a process crash in a shared RPC mdssvc worker process.

As RPC worker processes are shared among multiple client connections, a malicious client can crash the worker process affecting all other clients that are also served by this worker.
