global_motionblur.gani Crash

[ffcmike]

I believe there is a possibility global_motionblur.gani is being used by hacker(s) as a method to crash players clients, simply by setting it to their characters gani as opposed to its normal usage as a gani attribute.

While there are ways this could be detected by script, could this possibly be prevented in a more reliable way?
Maybe the gani's script could be modified to ensure it is not set to the players actual ani, like as follows:

PHP Code:

function onTimeout() {
  if(player.ani.name == "global_motionblur"){
    return;
  }
  //stuff
}

Judging by script, lolcursion occurs which looks quite easy to fix.

PHP Code:

SCRIPT
const TIMEGAP = 0.05;
const MOTIONSTEPS = 5;

function onPlayerEnters() {
  onTimeout();
}

function onTimeout() {
  this.counter = (this.counter + 1) % MOTIONSTEPS;
  if (player.ani.name != "global_motionblur") { // dat fix
    showTrail();
  } else {
    hideimgs(200,201+MOTIONSTEPS);
  } 
  setTimer(TIMEGAP);
}

function showTrail() {
  with (findimg(200 + this.counter)) {
    layer = 0;
    x = player.x;
    y = player.y;
    z = player.z;
    ani = player.ani.name @ "[" @ player.anistep @ "]";
    dir = player.dir;
    playerlook = true;
    actor.mode = 1;
  }

  for (temp.i=0; temp.i<MOTIONSTEPS; temp.i++)
    findimg(200 + (this.counter+1+temp.i)%MOTIONSTEPS).actor.alpha = 0.1 + 0.8*temp.i/MOTIONSTEPS;
}

Nice. All Stefan needs to do now is change one line in one file on one server. Maybe by Christmas?

I already realized this on iEra, but thought its just me. But than some days later it worked fine for me on another server so I didnt bother reporting this.
Well maybe I had a fixed one, not sure

I've updated and reloaded the file.

I actually emailed Stefan about this 3 or 4 months ago, but I never received a reply and I didn't notice any change in the bug's behaviour. Thanks for bringing this up Thor.
