Cusboonaysiinta saxda ah ayaa loo daabacay laanta BIND 9.16.18 deggan iyo laanta horumarka ee tijaabada ah ee 9.17.15, taas oo hagaajinaysa cayayaanka halista ah ee ka soo muuqday BIND 9.16.17 iyo 9.17.14 sii daynta la daabacay usbuucii hore (maalintii ka dambaysay tan sii daayo, horumariyayaashu waxay ka digeen dhibaatada waxayna ku taliyeen inaan la rakibin noocyada 9.16.17 iyo 9.17.14).
Noocyada 9.16.17 iyo 9.17.14, "w" waxa laga saaray miisaska khariidaynta xarfaha yaryar iyo kuwa waaweyn (maptoupper iyo maptolower), taas oo keentay in la beddelo xarfaha "W" iyo "w" ee magacyo domain oo leh taxanaha "\000" "iyo soo celinta natiijo aan sax ahayn marka la habeeyo codsiyada iyadoo la isticmaalayo maaskaro. Tusaale ahaan, haddii aagga DNS uu ka kooban yahay diiwaanka "*.sub.test.local. 1 A 127.0.0.1 "codsiga magaca UVW.sub.test.local" waxay soo saartay jawaab celinaysa magaca "uv/000.sub.test.local" halkii "uvw.sub.test.local".
Intaa waxaa dheer, dhibaatooyinka ayaa lagu xusay in lagu beddelo "w" dabeecadda "\000" inta lagu jiro cusboonaysiinta aagga firfircoon haddii kiiska "w" ee codsiga uu ka duwan yahay kiiska aagga DNS. Tusaale ahaan, haddii wax cusub loo soo diray "foo.ww.example" markii uu jiray diiwaan "WW.example" aagga, waxa loo farsameeyay sidii "foo.\000\000.tusaale." Dhibaatooyinka beddelka dabeecadda waxay sidoo kale dhici karaan marka la samaynayo wareejinta aaga ee aasaasiga ah ilaa server-ka DNS.
Daabacaada casriyeynta 9.16.18 ayaa dib u dhacday iyadoo ay ugu wacan tahay aqoonsiga laba khalad oo kale oo aan xal loo helin noocyada 9.16.18 iyo 9.17.15. Khaladaadku waxay keenaan xidhmo xidhmo ah inta lagu jiro bilawga waxayna ku dhacaan qaabaynta halka siyaasada dnssec ay isticmaasho aag isku mid ah oo ku jira aragtiyo kala duwan. Isticmaalayaasha leh goobahan waxaa lagula talinayaa inay hoos ugu dhigaan nooca BIND 9.16.16.
