All versions of package opcua; all versions of package asyncua are
vulnerable to Denial of Service (DoS) due to a missing limitation on the
number of received chunks - per single session or in total for all
concurrent sessions. An attacker can exploit this vulnerability by sending
an unlimited number of huge chunks (e.g. 2GB each) without sending the
Final closing chunk.
