Disclaimer: It is important to note that a previous vulnerability related to DoS attacks on asyncua servers exists.

#How was the vulnerability discovered ?
During my experiments for my Ph.D., I identified this vulnerability and promptly alerted the maintainers 
by creating an issue on Git, as their request.

#Reproduce:
To reproduce this vulnerability:
0/send a message with a size field set to 0.
I used an open secure channel request but others are working.


All of this is described in the issue:
The first comment made a mistake by thinking that this vulnerability is CVE-2022-25304. But if you read the complete issue
