Zosintha zowongolera zasindikizidwa kunthambi yokhazikika ya BIND 9.16.18 komanso nthambi yoyeserera yopititsa patsogolo 9.17.15, yomwe imakonza cholakwika chachikulu chomwe chidawonekera mu BIND 9.16.17 ndi 9.17.14 zotulutsidwa sabata yatha (tsiku lotsatira izi kutulutsa, opanga adachenjeza za vutoli ndipo adalimbikitsa kuti asayike mitundu 9.16.17 ndi 9.17.14).
M'matembenuzidwe a 9.16.17 ndi 9.17.14, zilembo za "w" sizinasiyidwe pamapu a zilembo zazing'ono komanso zazikulu kwambiri (maptoupper ndi maptolower), zomwe zidapangitsa kuti zilembo za "W" ndi "w" zilowe m'malo mwa mayina awo. mndandanda "\000" "ndikubweza zotsatira zolakwika pokonza zopempha pogwiritsa ntchito chigoba. Mwachitsanzo, ngati zone ya DNS ili ndi zolemba "*.sub.test.local. 1 Pempho la 127.0.0.1β³ la dzina la UVW.sub.test.local" lidapereka yankho lomwe lidabweza dzina "uv/000.sub.test.local" m'malo mwa "uvw.sub.test.local".
Kuonjezera apo, mavuto adadziwika posintha khalidwe la "w" ndi "\000" panthawi yosintha zone ngati nkhani ya "w" mu pempho ikusiyana ndi nkhani ya DNS zone. Mwachitsanzo, ngati zosintha zidatumizidwa za "foo.ww.example." pomwe panali mbiri "WW.example." m'zoni, idasinthidwa ngati "foo.\000\000.example.". Mavuto osintha mawonekedwe amathanso kuchitika posamutsa madera kuchokera pa pulayimale kupita ku seva yachiwiri ya DNS.
Kusindikizidwa kwa zosintha 9.16.18 kunachedwetsedwa chifukwa chozindikiritsa zolakwika zina ziwiri zomwe sizinathetsedwe m'matembenuzidwe 9.16.18 ndi 9.17.15. Zolakwika zimabweretsa kufa kwanthawi yayitali panthawi yoyambira komanso zimachitika m'masinthidwe pomwe dnssec-policy imagwiritsa ntchito madera omwewo omwe ali ndi malingaliro osiyanasiyana. Ogwiritsa omwe ali ndi zokonda zotere akulangizidwa kuti atsitse ku BIND mtundu 9.16.16.
