Google on v\u00e4lja andnud Chrome'i uuenduse 89.0.4389.128, milles on k\u00f5rvaldatud kaks haavatavust (CVE-2021-21206, CVE-2021-21220), mille jaoks on olemas valmis eksploidid (0-p\u00e4ev). Haavatavust CVE-2021-21220 kasutati Chrome'i h\u00e4kkimiseks Pwn2Own 2021 v\u00f5istlusel. <\/p>\n

Antud haavatavuse rakendamine toimub spetsiaalselt vormistatud WebAssembly koodi t\u00e4itmise kaudu (haavatavus on p\u00f5hjustatud veast WebAssembly virtuaalmasinas, mis v\u00f5imaldab andmete lugemist v\u00f5i kirjutamist suvalisse m\u00e4luaadressi). Tuleb m\u00e4rkida, et n\u00e4idatud eksploid ei v\u00f5imalda \u00fcletada sandbox-isolatsiooni ning t\u00e4ielikuks r\u00fcnnakuks on vajalik tuvastada veel \u00fcks haavatavus, et v\u00e4ljuda sandbox'ist (Pwn2Own 2021 v\u00f5istlusel demonstreeriti sellist haavatavust Windowsi jaoks). <\/p>\n

Antud probleemi eksploitimise n\u00e4ide avaldati GitHubis p\u00e4rast V8 mootoris tehtud paranduste tegemist, kuid ilma et oodati brauserite v\u00e4rskenduste v\u00e4ljat\u00f6\u00f6tamist (isegi kui eksploit ei oleks avaldatud, said r\u00fcndajad v\u00f5imaluse seda rekonstrueerida, anal\u00fc\u00fcsides V8 hoidlas toimunud muudatusi, nagu on varem juhtunud olukordade t\u00f5ttu, kus V8 parandused on juba avaldatud, kuid selle p\u00f5hjal toodetud tooted ei ole veel v\u00e4rskendatud). <\/p>\n

Lisaks v\u00f5ib m\u00e4rkida Chrome 90 v\u00e4ljalaske ajakava nihkumist Linuxile, Windowsile ja macOS-ile. See versioon oli planeeritud 13. aprilliks, kuid eile ei avaldatud seda ja v\u00e4lja anti ainult versioon Androidile. T\u00e4na loodi t\u00e4iendav Chrome 90 beetaversioon. Uue v\u00e4ljalaskekuup\u00e4eva kohta teavet ei anta.
