    CTorrent contains a stack-based buffer overflow in the

Impact :

    A remote attacker could entice a user to open a specially crafted
      torrent file using CTorrent, possibly resulting in execution of arbitrary
      code with the privileges of the process or a Denial of Service condition.
  
Workaround :
