Versions of the package asyncua before 0.9.96 are vulnerable to Denial of Service (DoS) such that an attacker can send a malformed packet and as a result, the server will enter into an infinite loop and consume excessive memory.
The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop.
