Konsekuensi Umum

Cakupan	Dampak	Kemungkinan
Availability	DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory), DoS: Amplification, DoS: Crash, Exit, or Restart Catatan: Excessive looping will cause unexpected consumption of resources, such as CPU cycles or memory. The product's operation may slow down, or cause a long time to respond. If limited resources such as memory are consumed for each iteration, the loop may eventually cause a crash or program exit due to exhaustion of resources, such as an out-of-memory error. In many cases, a loop does not need to be infinite in order to cause enough resource consumption to adversely affect the product or its host system; it depends on the amount of resources consumed per iteration.
