Er is een correctieve update beschikbaar voor de toolset voor het maken van zelfvoorzienende Flatpak-pakketten 1.10.2, waarin een kwetsbaarheid (CVE-2021-21381) is verholpen die de auteur van het pakket met de applicatie in staat stelt om de ingestelde sandbox-isolatie te omzeilen en toegang te krijgen tot bestanden in het onderliggende systeem. Het probleem doet zich voor vanaf versie 0.9.4. <\/p>\n

De kwetsbaarheid wordt veroorzaakt door een fout in de implementatie van de functie voor het doorverwijzen van bestandtoegang (\"file forwarding\"), die het mogelijk maakt om via manipulatie van het .desktop-bestand toegang te krijgen tot middelen in een externe bestandsomgeving, waar de uitvoerende toepassing geen toegang toe heeft. Bij het toevoegen van bestanden met de labels \"@@\" en \"@@u\" in het Exec-veld, zal flatpak aannemen dat de opgegeven doelbestanden expliciet door de gebruiker zijn aangegeven en automatisch toegang tot deze bestanden doorgeven in de sandbox. De kwetsbaarheid kan worden gebruikt door auteurs van schadelijke pakketten om toegang te organiseren tot externe bestanden, ondanks het schijnbare draaien in een ge\u00efsoleerde modus.
