Avalikustatud on teave Qubesi operatsioonis\u00fcsteemi haavatavuse kohta, mis kasutab h\u00fcperviisorit rakenduste ja OS komponentide rangeks isolatsiooniks (iga rakenduste klass ja s\u00fcsteemiteenused t\u00f6\u00f6tavad eraldi virtuaalmasinates). Kui r\u00fcndaja kompromiteerib \u00fche virtuaalmasina, v\u00f5imaldab haavatavus isolatsiooni \u00fcletada, saavutada juhuslike k\u00e4skude t\u00e4itmist host-\u00fcmbrikus (Dom0) ning saada kontroll kogu operatsioonis\u00fcsteemi \u00fcle. Probleem ilmneb, kui kasutaja kasutab utiliiti «qvm-copy-to-vm» faili kopeerimiseks host-\u00fcmbrikust r\u00fcndaja kontrollitavasse virtuaalmasinasse. Haavatavus on k\u00f5rvaldatud paketi qubes-core-dom0-linux 4.3.22 v\u00e4rskenduses. <\/p>\n

Probleem esineb utiliidis «qvm-copy-to-vm» ja on p\u00f5hjustatud vigadest, mis tekivad, kui p\u00f6\u00f6rduda virtuaalses masinas<\/a>. Turvaauk seisneb selles, et utiliit qvm-copy-to-vm k\u00e4ivitas veateabe kuvamiseks programmid kdialog v\u00f5i zenity, kasutades funktsiooni system() ja lisades tasule viidatud eba\u00f5nnestunud faili teavet k\u00e4surea valikutesse. Failinime puhastamine piirdus mitte-ASCII-m\u00e4rkide ja kaheteistk\u00fcmnenda jutum\u00e4rgi eemaldamisega, ilma et oleks kontrollitud spetsiaalsete m\u00e4rkide olemasolu, mida t\u00f5lgendab k\u00e4surea keskkond, nagu «`» ja «$». <\/p>\n

P\u00e4rast failide kopeerimise l\u00f5petamist edastab virtuaalmasina k\u00fclgpaneel tagasi teate operatsiooni kinnitamisest, kus muuhulgas on m\u00e4rgitud viimase vastu v\u00f5etud faili nimi. R\u00fcnnak seisneb veakoodi tagastamises kinnituse asemel ja faili jaoks, mida ei \u00f5nnestunud kopeerida, nimega, kus on k\u00e4surea t\u00f5lgendamiseks spetsiaalsed s\u00fcmbolid. P\u00e4rast veateate saamist k\u00e4ivitab host-\u00fcmbriku k\u00fclgpaneel k\u00e4suga system() utiliidi, et kuvada dialooge, edastades k\u00e4sureas r\u00fcndaja tagastatud faili nime (n\u00e4iteks kui on m\u00e4rgitud «file`id`», siis k\u00e4ivitub host-\u00fcmbrikus k\u00e4sk id).
