Description Jan Lieskovsky 2010-07-21 11:37:52 EDT
User with nickname 'Dolly' reported:
  [1] http://bugs.openttd.org/task/3909

a deficiency in the way OpenTTD transportation business simulation game
server synced local command queue to the command queue of the given socket
after receiving a command from a game joining client. A remote attacker
could use this flaw to conduct denial of service attacks, leading to game
server infinite loop consuming excessive amount of CPU time.

Proposed patch:

      upstream review and may change in final form)
