  Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS)
  condition due to the Snort process unexpectedly restarting.

  The vulnerability is due to improper handling of an HTTP packet stream. An attacker could exploit
  this vulnerability by sending a crafted HTTP packet stream to the detection engine on the targeted
  device. An exploit could allow the attacker to cause a DoS condition if the Snort process restarts
  and traffic inspection is bypassed or traffic is dropped.

  Cisco has released software updates that address this vulnerability. There are no workarounds that
  address this vulnerability.");
