If this is applied in a cronjob or within a PHP calling an external program or in a CGI, generally there are no limits to resource usage, so the machine goes down. An attacker might state that he will shutdown or restart your machine (which can only be done with root access), but instead he just renders the machine unusable.
Kama hii ni kutumika katika cronjob au ndani ya PHP wito mpango nje au katika CGI, ujumla hakuna mipaka na matumizi ya maliasili, hivyo mashine inakwenda chini. mshambulizi anaweza hali ya kuwa yeye shutdown au kuanzisha upya mashine yako (ambayo inaweza tu kufanyika kwa kupata mizizi), lakini badala yake yeye tu mithili mashine kutotumika.
