I did a test before sending the email and after the alias was created the 
listdeaths command did nothing. Is same fix suggested by 1nsane for floods 
using status command. You only need a plugin if you want to log or to ban the 
players…

I just tried the alias listdeaths "" command, executed it via RCON but I was 
still able to crash my server even by entering the listdeaths command once on 
client side. It didn't seem to matter how long the server was up, it would 
still crash regardless.

 

I ended up making a small SourceMod plugin which blocks the command and logs 
the client who did it. That seemed to do the trick for me. Feel free to look at 
the source code and compile it yourself.

So that line in the server.cfg is all that's needed until this is patched?  If 
so, thank you very much for that.

Add this line to server’s config for a fast/easy fix:

 

alias listdeaths ""

 

Type the alias command to server’s console too, otherwise the server will be 
vulnerable until map changes.

Saw this via Reddit, and this can crash a server within seconds. I hope this 
can be patched soon.

 

Steps: 

This is all done in the console, or it can be done in autoexec

alias crash 
"listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths;listdeaths"

then you simply

bind u "crash"

This will display a lot of crap in the console of all the deaths that have 
occurred so far. Especially on 24/7 servers.
