I PackageKit, D-Bus-laget der standardiserer pakkeh\u00e5ndteringsoperationer, er der opdaget en s\u00e5rbarhed Pack2TheRoot (CVE-2026-41651), der g\u00f8r det muligt for en ikke-privilegeret bruger at installere eller fjerne vilk\u00e5rlige pakker og f\u00e5 root-adgang til systemet. Problemet opst\u00e5r fra version 1.0.2 (2014) og er blevet rettet i version 1.3.5 af PackageKit. <\/p>\n

Problemet blev identificeret af forskere fra Deutsche Telekom ved hj\u00e6lp af AI-modellen Claude Opus. Der er udarbejdet et fungerende exploit, der virker p\u00e5 de fleste distributioner med PackageKit, men b\u00e5de det og detaljerede oplysninger om s\u00e5rbarheden planl\u00e6gges offentliggjort senere for at give brugerne tid til at opdatere deres systemer. Muligheden for at udnytte s\u00e5rbarheden blev demonstreret i Ubuntu Desktop 18.04\/24.04.4\/26.04, Ubuntu Server 22.04 \u2013 24.04, Debian Desktop 13.4, RockyLinux Desktop 10.1 og Fedora 43 Desktop\/Server. Status for udbedring af s\u00e5rbarheder i distributionerne kan vurderes p\u00e5 disse sider (hvis siden ikke er tilg\u00e6ngelig, betyder det, at udviklerne af distributionen endnu ikke er g\u00e5et i gang med at behandle problemet): Debian, Ubuntu, SUSE, RHEL, Gentoo, Arch, Fedora, FreeBSD. <\/p>\n

S\u00e5rbarheden skyldes en race-tilstand under behandling af transaktionsflagg i baggrundsprocessen af PackageKit, hvilket muligg\u00f8r \u00e6ndring af operationsparametrene i det \u00f8jeblik, hvor godkendelsen sker, og indtil operationen med pakken starter. Angriberen kan sende en D-Bus-foresp\u00f8rgsel for at udf\u00f8re en operation, der er tilladt for en ikke-privilegeret bruger, hvorefter de kan sende en gentagen D-Bus-foresp\u00f8rgsel. Hvis den gentagne foresp\u00f8rgsel kommer f\u00f8r den faktiske start af den tilladte operation, kan flagene for den allerede startede transaktion blive overskrevet, hvilket \u00e6ndrer den cachede tilstand. <\/p>\n

Dermed vil en allerede igangsat tilladt transaktion blive udf\u00f8rt med ikke-oprindelige parametre, men med de \u00e6ndrede parametre, der blev sendt i den anden foresp\u00f8rgsel. Ved at \u00e6ndre oplysningerne om den installerede pakke kan man i stedet for den tilladte pakke installere en hvilken som helst anden pakke, herunder en lokal pakke gemt af angriberen. Installation af pakken udf\u00f8res med root-rettigheder, s\u00e5 for at f\u00e5 root-adgang til systemet kan angriberen tilf\u00f8je sin egen scriptlet til pakken, der automatisk k\u00f8res f\u00f8r eller efter installationen.
