Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in the refill function when processing LZ4 block streams with stopOnEmptyBlock set to false. An attacker can cause a thread to terminate unexpectedly by providing a stream with a large number of consecutive empty blocks, leading to stack exhaustion and application unavailability. This is only exploitable if the configuration option stopOnEmptyBlock is explicitly set to false.
