Turvauuringute ekspert Cisco ettev\u00f5ttest avalikustas<\/a><\/noindex> teave haavatavuse kohta (CVE-2019-5021) kogudes<\/a><\/noindex> Alpine jaotuses konteinerite isoleerimise s\u00fcsteemi jaoks Docker. Tuvastatud probleem seisneb selles, et kasutaja root jaoks on vaikimisi m\u00e4\u00e4ratud t\u00fchi parool, mis ei takista otsest sisenemist root-kontole. Tootjatega Alpine kasutatakse ametlike Docker-projektide piltide loomisel (varem p\u00f5hinesid ametlikud kogumid Ubuntu-l, kuid hiljem olid t\u00f5lgitud<\/a><\/noindex> Alpine'il.<\/p>\n

Probleem ilmnes alates Alpine Docker versioonist 3.3 ja see oli p\u00f5hjustatud 2015. aastal tehtud regressiivsest muutusest (enne versiooni 3.3 kasutati failis \/etc\/shadow rida «root:!::0:::::», kuid p\u00e4rast -d lipu kasutamise l\u00f5petamist lisandub rida «root:::0:::::»). Probleem tuvastati esmakordselt ja parandatud<\/a><\/noindex> novembri 2015. aastal, kuid detsembris anti kogemata uuesti kerkinud<\/a><\/noindex> katsetusversiooni kogumifailidesse, ning seej\u00e4rel viidi see stabiilsetesse kogudesse.<\/p>\n

Teave haavatavuse kohta n\u00e4itab, et probleem esineb ka Alpine Docker 3.9 viimases harus. Alpine arendajad m\u00e4rtsis v\u00e4lja andsid<\/a><\/noindex> paranduse ja haavatavuse ei ilmne<\/a><\/noindex> Alustades versioonidest 3.9.2, 3.8.4, 3.7.3 ja 3.6.5, kuid j\u00e4\u00e4b vanadesse harudesse 3.4.x ja 3.5.x, mille tugi on juba l\u00f5petatud. Lisaks v\u00e4idavad arendajad, et r\u00fcnnakuks vajalik vektor on tugevalt piiratud ja n\u00f5uab, et r\u00fcndajal oleks juurdep\u00e4\u00e4s samale infrastrukturile.<\/p>\n
