Google on v\u00e4lja andnud Chrome 89.0.4389.128 versiooniuuenduse, mille k\u00e4igus on parandatud kaks turvaauku (CVE-2021-21206, CVE-2021-21220), mille jaoks on olemas t\u00f6\u00f6tavad eksploidid (0-day). Turvaauk CVE-2021-21220 kasutati Chrome'i h\u00e4kkimiseks Pwn2Own 2021 v\u00f5istlusel. <\/p>\n

Antud turvaaugu ekspluateerimine toimub kindlal viisil vormistatud WebAssembly koodi t\u00e4itmise kaudu (turvaauk tuleneb veast WebAssembly virtuaalmasinas, mis v\u00f5imaldab kirjutada v\u00f5i lugeda andmeid suvalisest m\u00e4luaadressist). Samuti on m\u00e4rgitud, et esitatud eksploit ei v\u00f5imalda m\u00f6\u00f6da minna liivakasti isoleerimisest ning t\u00e4ieliku r\u00fcnnaku jaoks on vajalik avastada veel \u00fcks turvaauk liivakastist v\u00e4ljap\u00e4\u00e4semiseks (Pwn2Own 2021 v\u00f5istlusel demonstreeriti sellist turvaauku Windowsi jaoks). <\/p>\n

N\u00e4ide eksploidist selle probleemi jaoks avaldati GitHubis p\u00e4rast V8 mootori paranduse tegemist, kuid enne, kui brauserite uuendamine selle p\u00f5hjal toimus (isegi kui eksploit ei oleks avaldatud, said kurjategijad v\u00f5imaluse selle taastada V8 hoidla muudatuste anal\u00fc\u00fcsi p\u00f5hjal, nagu on varemgi juhtunud, juhul kui V8 parandused on juba avaldatud, kuid selle p\u00f5hjal loodud tooted pole veel uuendatud). <\/p>\n

Lisaks v\u00f5ib m\u00e4rkida, et Chrome 90 v\u00e4ljaandmise ajakava on muutunud Linuxi, Windowsi ja macOS-i jaoks. See v\u00e4ljaanne oli kavandatud 13. aprilliks, kuid eile ei avaldatud seda, ja avaldati vaid versioon Androidile. T\u00e4na on loodud t\u00e4iendav beetaversioon Chrome 90-le. Uue v\u00e4ljalaskekuup\u00e4eva kohta teavet ei edastata.
