Ein korrektives Update f\u00fcr das Toolkit zur Erstellung von eigenst\u00e4ndigen Flatpak-Paketen 1.10.2 ist verf\u00fcgbar, das eine Schwachstelle (CVE-2021-21381) behoben hat. Diese erlaubt es dem Paketautor, den installierten Sandbox-Isolationsmodus zu umgehen und auf Dateien im Hauptsystem zuzugreifen. Das Problem tritt seit der Version 0.9.4 auf. <\/p>\n

Die Schwachstelle wird durch einen Fehler in der Implementierung der Dateizugriffsweiterleitungsfunktion (\u00bbfile forwarding\u00ab) verursacht, die es erm\u00f6glicht, \u00fcber Manipulation mit .desktop-Dateien auf Ressourcen im externen Dateisystem zuzugreifen, auf die das gestartete Programm keinen Zugriff haben sollte. Durch das Hinzuf\u00fcgen von Dateien mit den Markierungen \u00bb@@\u00ab und \u00bb@@u\u00ab im Exec-Feld betrachtet flatpak die angegebenen Ziel-Dateien als explizit vom Benutzer angegeben und gew\u00e4hrt automatisch Zugriff auf diese Dateien im Sandbox-Modus. Die Schwachstelle kann von Autoren b\u00f6sartiger Pakete ausgenutzt werden, um Zugang zu externen Dateien zu erlangen, obwohl die Anwendung anscheinend im Isolationsmodus l\u00e4uft.
