iperf3: iperf3 server accepts unbounded peer-controlled JSON parameters enabling remote denial of service via resource exhaustion

A flaw was found in iperf3. A remote attacker can exploit this vulnerability by sending crafted control-channel JSON with oversized numeric parameters, such as parallel and len, which are not properly validated by the server. This improper input validation can lead to excessive stream and thread...
