Overview

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') via the PATH_CHALLENGE frame processing. An attacker can cause excessive resource consumption by sending PATH_CHALLENGE frames and manipulating the connection to slow down the rate at which PATH_RESPONSE frames are sent, resulting in an unbounded queue of path validation data.
