Runc, mis kasutatakse isoleeritud konteinerite k\u00e4itamiseks Dockeris ja Kuberneteses, on tuvastatud haavatavus (CVE-2021-30465), mis v\u00f5imaldab konteinerist p\u00e4\u00e4seda host-\u00fcmbruse p\u00f5hifailis\u00fcsteemi.

Haavatavuse \u00e4rakasutamiseks peab r\u00fcndaja olema suuteline k\u00e4itama konteineri konfiguratsioonis t\u00e4iendavaid monteerimispunkte (nt probleem esineb Kubernetesel p\u00f5hinevates keskkondades, kus kasutajad saavad oma konteinerid k\u00e4ivitada). Monteerimist punktide kontrollimise ja nende kasutamise vahel on olemas ajakenkus, mis jagatakse teiste konteineritega, ning r\u00fcndaja saab konteineri k\u00e4ivitamise ajal seda kasutada, et asendada montaa\u017eis kasutatav kataloog s\u00fcmboolse lingiga, mis viib v\u00e4ljaspool konteineri failis\u00fcsteemi juurt.
