H Denial of Service (DoS) node-opcua is an implementation of a OPC UA stack fully written in javascript and nodejs Affected versions of this package 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. How to fix Denial of Service (DoS)? Upgrade `node-opcua` to version 2.74.0 or higher.	<2.74.0
H Denial of Service (DoS) node-opcua is an implementation of a OPC UA stack fully written in javascript and nodejs Affected versions of this package are vulnerable to Denial of Service (DoS) by sending a specifically crafted OPC UA message with a special OPC UA `NodeID`, when the requested memory allocation exceeds the v8’s memory limit. How to fix Denial of Service (DoS)? Upgrade `node-opcua` to version 2.74.0 or higher.	<2.74.0
H Denial of Service (DoS) node-opcua is an implementation of a OPC UA stack fully written in javascript and nodejs Affected versions of this package are vulnerable to Denial of Service (DoS) when bypassing the limitations for excessive memory consumption by sending multiple `CloseSession` requests with the `deleteSubscription` parameter equal to `False`. How to fix Denial of Service (DoS)? Upgrade `node-opcua` to version 2.74.0 or higher.	<2.74.0
