Overview

Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value in the readLength parameter when pipe_air_gap_receiver_enabled is set to true. An attacker can exhaust heap memory and cause the DataNode process to crash or become severely degraded by sending unauthenticated TCP connections with attacker-controlled large allocation requests to port 9780.
