CoreWCF: Kafka consume pump halts permanently on a Kafka tombstone (null-value record), causing persistent endpoint denial of service.

Description

### Impact A CoreWCF service is running and listening on a Kafka topic receiving a null-value record will stop processing new records from that topic. #### Preconditions The attacker has produce/write permission on a topic that CoreWCF is consuming from. If the broker permits anonymous publishes, no authentication is required. ### Patches Fixed in CoreWCF v1.8.1 and v1.9.1 ### Workarounds Only allow authenticated writes to a topic
