Vulnerability	Vulnerable Version
H Loop with Unreachable Exit Condition ('Infinite Loop') Affected versions of this package are vulnerable to Loop with Unreachable Exit Condition ('Infinite Loop') 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. Note: When the attack is performed, no other client is able to reach the server. For a device with limited resources, it can lead to a crash of the device. How to fix Loop with Unreachable Exit Condition ('Infinite Loop')? Upgrade `asyncua` to version 0.9.96 or higher.	[,0.9.96)
M Improper Authentication Affected versions of this package are vulnerable to Improper Authentication such that it is possible to access Address Space without encryption and authentication. Note: This issue is a result of missing checks for services that require an active session. How to fix Improper Authentication? Upgrade `asyncua` to version 0.9.96 or higher.	[,0.9.96)
H Denial of Service (DoS) 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 `asyncua` to version 0.9.96 or higher.	[,0.9.96)
