There's a new exploit that a normal use can use to crash the kernel, and lock up the system.
It's a small C/C++ program, so basically you can just copy the code to clipboard, copy it into a file, and gcc -o crash crash.txt to get it working
>_<
So basically I want to stop users from compiling and running applications they upload. =D
Thanks!

make gcc only usable by root and a group by using chown ... then they would have to upload a new gcc to do that (which they could do if they wanted to).
I don't allow anyone access to anything on my server except the webpages...

remove the executable flag from all the files uploaded by users.
