Turvalisuuringute spetsialistid ettev\u00f5ttest Cisco avaldasid<\/a><\/noindex> teave haavatavuse (CVE-2019-5021) kohta versioonides<\/a><\/noindex> Alpine distributsioon Docker konteinerite isoleerimise s\u00fcsteemile. Tuvastatud probleem seisneb selles, et kasutaja root jaoks oli vaikes\u00e4tetena m\u00e4\u00e4ratud t\u00fchi parool ilma otse juurdep\u00e4\u00e4su blokeerimiseta. Meenutame, et Alpine'i kasutatakse Docker projekti ametlike piltide loomiseks (varem p\u00f5hinesid ametlikud versioonid Ubuntu'l, kuid hiljem viidi \u00fcle<\/a><\/noindex> Alpine'ile).<\/p>\n

Probleem ilmneb alates Alpine Docker 3.3 versioonist ning see oli p\u00f5hjustatud 2015. aastal lisatud tagurpidi muudatusest (enne versiooni 3.3 kasutati \/etc\/shadow failis rida «root:!::0:::::», kuid p\u00e4rast -d lipu kaotamist hakati lisama rida «root:::0:::::»). Probleem avastati algselt ja parandatud<\/a><\/noindex> 2015. aasta novembris, kuid detsembris kantakse see kogemata tagasi ilmnes<\/a><\/noindex> katsetamise haru versioonifailidesse ja hiljem viidi see stabiilsetesse versioonidesse.<\/p>\n

Teabetes haavatavuse kohta on m\u00e4rgitud, et probleem ilmneb ka Alpine Docker versioonis 3.9. Alpine arendajad parandasid arendajad muusikateenusest Spotify. Muudetud Spotify Lite n\u00e4eb v\u00e4lja nagu t\u00e4isversioon, kuid on ilma paljusid seadeid ja ei luba salvestada lugusid kuulamiseks ilma interneti\u00fchenduseta.<\/a><\/noindex> haavatavuse ja see ei ilmne<\/a><\/noindex> versioonides 3.9.2, 3.8.4, 3.7.3 ja 3.6.5, kuid j\u00e4\u00e4b endiselt vanadesse harudesse 3.4.x ja 3.5.x, mille toetamine on juba l\u00f5petatud. Lisaks v\u00e4idavad arendajad, et r\u00fcnnakuks vajalikud v\u00f5imalused on tugevalt piiratud ja n\u00f5uavad r\u00fcndajalt juurdep\u00e4\u00e4su samasse infrastruktuuri.<\/p>\n
