Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. From 4.0.0 until 4.3.0, EurekaDiscoveryClient deserializes the registry response as one unit, and an unrecognized actionType or status, a non-Boolean isCoordinatingDiscoveryServer, or a nonnumeric timestamp can abort the entire response. A principal that can register or update an instance can cause all connected Steeltoe clients to receive an empty or stale instance list until the malformed registration is removed. The JsonInstanceInfoConverter, BoolStringJsonConverter, and LongStringJsonConverter parsing paths are affected. This issue is distinct from the earlier DataCenterInfo.name parsing vulnerability. This issue is fixed in version 4.3.0.
