CRI-O-s, isoleeritud konteinerite haldamiseks m\u00f5eldud k\u00e4itamisajad, on avastatud kriitiline haavatavus (CVE-2022-0811), mis v\u00f5imaldab isolamento vahele j\u00e4tta ja k\u00e4ivitada oma koodi host-s\u00fcsteemi k\u00fcljes. Kui CRI-O-d kasutatakse containerd ja Docker asemel konteinerite k\u00e4itamiseks, mis t\u00f6\u00f6tab Kubernetes'i platvormi all, v\u00f5ib r\u00fcndaja saada kontrolli \u00fcle mis tahes s\u00f5lme Kubernetes'i klastris. R\u00fcnnaku l\u00e4biviimiseks piisab \u00f5igustest oma konteineri k\u00e4ivitamiseks Kubernetes'i klastris. <\/p>\n

Haavatavus tuleneb v\u00f5imalusest muuta s\u00fcsteemi kontrolli parameetrit \"kernel.core_pattern\" (\"\/proc\/sys\/kernel\/core_pattern\"), millele juurdep\u00e4\u00e4s ei olnud blokeeritud, kuigi see ei kuulu nende ohutute parameetrite hulka, mida on lubatud muuta ainult praeguse konteineri nimetes. Selle parameetri abil saab konteinerist kasutaja muuta Linuxi tuuma k\u00e4itumist core-failide t\u00f6\u00f6tlemisel host-\u00fcmbritsemise poolel ja k\u00e4ivitada suvalise k\u00e4su root \u00f5igustes hostis, m\u00e4\u00e4rates k\u00e4itleja t\u00fc\u00fcpi \"|\/bin\/sh -c 'komandid'\". <\/p>\n

Probleem ilmnes alates CRI-O versioonist 1.19.0 ja see on k\u00f5rvaldatud uuendustes 1.19.6, 1.20.7, 1.21.6, 1.22.3, 1.23.2 ja 1.24.0. Distributsioonides ilmneb probleem toodetes Red Hat OpenShift Container Platform ja openSUSE\/SUSE, mille hoidlatest leiate paketi cri-o.
