  This version is prone to a stack-based buffer overrun vulnerability.
  An attacker, exploiting this flaw, would need network access to the
  server as well as the ability to send a crafted transaction packet
  to the cfservd process. A successful exploitation of this flaw
  would lead to arbitrary code being executed on the remote machine
  or a loss of service (DoS).");
