Today I fixed an issue that could be used to cause a server to crash.
I will not go into detail, as I do not wish to spread how this was done in case the wrong person sees and gets to servers before they update.
I strongly recommend updating your ULIB to the most recent update on GIT.
There were no changes made (TODAY) to ULX, so you don't need to update ULX unless you want to.
