Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion via the readLength function. An attacker can exhaust the receiver thread's JVM stack and cause a StackOverflowError by sending a stream of repeated E-language prefixes to the socket, resulting in unbounded recursion.
Note: This is only exploitable if the configuration setting pipe_air_gap_receiver_enabled is set to true.
