Overview
Affected versions of this package are vulnerable to Stack-based Buffer Overflow due to improper input validation of the message buffer length, which can result in a buffer overflow. An attacker can achieve stack corruption or potentially execute arbitrary code by sending specially crafted input to the affected application.
Note: This is only exploitable if the attacker has access to a valid network key.
