Izolo ntambama, isikhathi saseSpain, inkampani eseCupertino ikhiphe i-iOS 12.1.4, isibuyekezo ebesilindelwe isikhathi eside esixazulule Inkinga yokuphepha ye-FaceTime itholakale ku-iOS futhi lokho kuvumela othumela ucingo, khetha ngokuzenzakalela lapho ufaka umuntu wesithathu kuyo, ukuze Amaseva we-Apple futhi avumela izingcingo zeqembu.
Ngasinye, kuphela phakathi kwamadivayisi aphethwe yi-iOS 12.1.4. Uma ngabe idivayisi yakho ingalawulwa yileyo nguqulo, izingcingo zeqembu nge-FaceTime azitholakali ngaphandle kokuthi uthuthukise. Kepha kubonakala sengathi lokhu kubuyekezwa kwakamuva, akugcini nje ngokulungisa inkinga yezingcingo, kepha futhi, ngokusho konjiniyela wezokuphepha wakwaGoogle, ilungisa ukuba sengozini kwezinsuku ezimbili.
Ukuba sengozini kwezinsuku ezi-0 (usuku olungu-zero) yikhona okukhona kuzinhlelo zokusebenza noma kumasistimu asebenzayo ngoba ayatholakala emphakathini ngaphandle kokuthi unjiniyela ayazi, ngakho-ke bebehlala betholakala ukuxhaphaza, yingakho bebizwa ngezinsuku ezi-0 (usuku olungu-zero).
Uma ngabe unokungabaza mayelana nokuthi ungabuyekeza i-iOS 12.1.4 noma cha, ukuba khona kwalezi zingcuphe ezimbili kungobunye ubufakazi bokuthi kuhlale kunconywa ukuvuselela uhlelo lwethu lokusebenza enguqulweni yakamuva etholakalayo, uhlelo lokusebenza esilusebenzisayo kanye nolwezinhlelo zokusebenza.
UBen Hawker, unjiniyela wezokuphepha wakwa-Google obike ngalezi zinkinga ezimbili, ezikhonjwe njenge-CVE-2019-7286 ne-CVE-2019-7287, uthi owokuqala uvumela umuntu wesithathu ukuthi asebenzise inkohlakalo yememori thola amalungelo aphezulu.
Owesibili, uvumela umhlaseli yenza ikhodi engenacala ngamalungelo we-kernel, ngenxa yenkinga yenkohlakalo yenkumbulo ngenhla. Ngokusobala, ayisekho imininingwane enikeziwe ngenxa yokubaluleka kwalolu hlobo lokuba sengozini nokuthi amadivayisi amaningi awakavuselelwa.
Lezi zinkinga zokuphepha zitholwe yiGoogle ngokusebenzisa ipulatifomu yeProject Zero, ipulatifomu enesibopho sokuthola amaphutha ezokuphepha kuzona zombili izinhlelo zokusebenza nezinhlelo zokusebenza nokwazisa ngaphambilini labo abathintekile, ibanikeze isikhathi sezinsuku ezingama-90 ukuxazulula inkinga ngaphambi kokuyibeka esidlangalaleni.
