Kuphatikiza pazatsopano ndi kukonza zolakwika, mtundu watsopano umachotsa zovuta 52. Zofooka zambiri zidadziwika chifukwa choyesera zokha pogwiritsa ntchito AddressSanitizer, MemorySanitizer, Control Flow Integrity, LibFuzzer ndi zida za AFL. Nkhani imodzi (CVE-2019-5870) yadziwika kuti ndi yovuta, mwachitsanzo. imakupatsani mwayi wodutsa magawo onse achitetezo cha asakatuli ndikuchita ma code pa system kunja kwa sandbox. Tsatanetsatane wa chiwopsezo chachikulu sichinafotokozedwe; zimangodziwika kuti zitha kubweretsa mwayi wofikira kumalo omasulidwa kale mu code multimedia data processing. Monga gawo la pulogalamu yolipira mphotho zandalama pozindikira zovuta zomwe zatulutsidwa pano, Google idapereka mphotho 38 zokwana $33500 (mphotho imodzi ya $7500, mphotho zinayi za $3000, mphotho zitatu za $2000, mphotho zinayi za $1000 ndi mphotho zisanu ndi zitatu za $500). Kukula kwa mphotho 18 sikunadziwikebe.
