  headers. An attacker could exploit this vulnerability by sending a crafted SIP packet to a targeted system.
  A successful exploit could allow the attacker to cause the sipd process to restart unexpectedly, resulting
  in a DoS condition on the system. If the sipd process restarts repeatedly, a successful exploit could also
  result in a sustained DoS condition and cause high disk utilization due to a large number of sipd core files
  being written to disk, which could exacerbate the DoS condition.");
