Stack Pointer<\/h1>\n

Korstnapoider on arvuti arhitektuuri oluline komponent, mis vastutab korstna haldamise eest. andmed<\/a> struktuur. Korstnat on m\u00e4lupiirkond, mida arvutiprogrammid kasutavad ajutiste andmete, n\u00e4iteks funktsioonik\u00f5ne raamide, lokaalsete muutujate ja tagasip\u00f6\u00f6rdumisaadresside hoidmiseks. Korstnapoider on register, mis hoiab korstna \u00fclemise osa m\u00e4luaadressi, mis on koht, kuhu j\u00e4rgmine element korstnast l\u00fckatakse v\u00f5i kustutatakse.<\/p>\n

Korstnapoolt rakendatakse tavaliselt protsessori eriotstarbelise registrina, mida operatsioonis\u00fcsteem ja kompilaator kasutavad korstna haldamiseks. Kui funktsiooni kutsutakse, kasutatakse virna n\u00e4itajat selleks, et eraldada virnas ruumi funktsiooni lokaalsetele muutujatele ja salvestada tagasip\u00f6\u00f6rdumisaadressi. Kui funktsioon naaseb, kasutatakse korstnapoolt korstnapunkti ruumi vabastamiseks ja programmi eelmise seisundi taastamiseks.<\/p>\n

Korstnapoider on arvutiturbe kriitiline komponent, kuna seda kasutatakse sageli tarkvara haavatavuste \u00e4rakasutamiseks. Stack-p\u00f5hised puhvri \u00fclevoolur\u00fcnnakud tuginevad n\u00e4iteks korstnas oleva tagasip\u00f6\u00f6rdumisaadressi \u00fclekirjutamisele, et suunata programmi t\u00e4itmisvoog \u00fcmber pahatahtlikule kood<\/a>. Selliste r\u00fcnnakute v\u00e4ltimiseks rakendavad kaasaegsed operatsioonis\u00fcsteemid ja kompilaatorid mitmesuguseid turvamehhanisme, n\u00e4iteks korstnap\u00f5hiseid kanarbeid, aadressiruumi paigutuse juhuslikustamist (ASLR) ja mittet\u00e4itvat m\u00e4lu (NX), mis raskendavad r\u00fcndajate jaoks korstnap\u00f5histe haavatavuste \u00e4rakasutamist.<\/p>\n
