Another “critical” “VPN” “vulnerability” and why Port Fail is bullshit

Is it possible to exploit port 0 on either UDP or TCP. Instead of hard-coding a particular port number, or writing code that searches for an available port on the local system, network programmers can instead specify port 0 as a connection parameter. That triggers the operating system to automatically search for and return the next available port in the dynamic port number range. Have fun guys ;)
