Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the SelectorSocketTransport.writelines() method not draining its buffers, when Protocols are in use. An attacker can cause this behavior which eventually exhausts available memory by continuously writing data without triggering the buffer drain mechanism.
Note: This is only exploitable on macOS and Linux.
