Avaldatud on APT pakendihalduri paranduste versioonid, mis lahendavad haavatavuse (CVE-2026-109518), mis v\u00f5imaldab m\u00f6\u00f6da minna kontrollist failide allalaadimisel ja saavutada oma koodi k\u00e4ivitamine root \u00f5igustes. Kokku on loodud 13 v\u00e4ljaannet, mis katab k\u00f5ik viimase 10 aasta APT harud alates 1.2.x. Pakettide uuendused haavatavuse k\u00f5rvaldamiseks on juba koostatud ka erinevate versioonide jaoks nagu Debian, Ubuntu ja Deepin. Vaikimisi konfiguratsioonis puudutab probleem k\u00f5iki v\u00e4ljaandeid alates Debian 12 ja Ubuntu 22.04. Vanemate versioonide \u00e4rakasutamine on v\u00f5imalik juhul, kui Acquire::Retries parameetriks seada v\u00e4\u00e4rtus suurem kui 0.<\/p>\n

Haavatavuse raportis ei mainita detailselt probleemi, on vaid \u00f6eldud, et see on tingitud valest haldamisest k\u00f5vade linkidega.
