El problema se presenta a partir de la versi\u00f3n 1.0.2 (a\u00f1o 2014) y se ha corregido en la versi\u00f3n 1.3.5 de PackageKit.    <\/p>\n<p>Problema identificada por investigadores de Deutsche Telekom mediante el modelo de IA Claude Opus. Se ha preparado un exploit funcional que opera en la mayor\u00eda de las distribuciones con PackageKit, pero se planea publicar informaci\u00f3n detallada sobre la vulnerabilidad m\u00e1s adelante, para dar tiempo a los usuarios a actualizar sus sistemas. La posibilidad de explotar la vulnerabilidad se ha demostrado en Ubuntu Desktop 18.04\/24.04.4\/26.04, Ubuntu Server 22.04 \u2014 24.04, Debian Desktop 13.4, RockyLinux Desktop 10.1 y Fedora 43 Desktop\/Server. El estado de la correcci\u00f3n de vulnerabilidades en las distribuciones se puede evaluar en estas p\u00e1ginas (si la p\u00e1gina no est\u00e1 disponible, significa que los desarrolladores de la distribuci\u00f3n a\u00fan no han comenzado a abordar el problema): Debian, Ubuntu, SUSE, RHEL, Gentoo, Arch, Fedora, FreeBSD.      <\/p>\n<p>La vulnerabilidad es causada por una condici\u00f3n de carrera en el manejo de las banderas de transacci\u00f3n en el proceso en segundo plano de PackageKit, lo que permite alterar los par\u00e1metros de la operaci\u00f3n en el momento entre la autorizaci\u00f3n y la ejecuci\u00f3n de la operaci\u00f3n con el paquete. Un atacante puede enviar una solicitud D-Bus para ejecutar una operaci\u00f3n permitida para un usuario no privilegiado y luego enviar una solicitud D-Bus repetida. Si la solicitud repetida llega antes de que comience realmente la operaci\u00f3n permitida, se puede lograr la redefinici\u00f3n de las banderas de una transacci\u00f3n ya iniciada y alterar el estado en cach\u00e9.     <\/p>\n<p>De este modo, una transacci\u00f3n permitida que ya ha comenzado se ejecutar\u00e1 con par\u00e1metros alterados en lugar de los originales, utilizando los par\u00e1metros del segundo pedido. Al alterar la informaci\u00f3n del paquete a instalar, se puede sustituir el paquete permitido por cualquier otro, incluido uno guardado localmente por el atacante. La instalaci\u00f3n del paquete se lleva a cabo con privilegios de root, por lo que para obtener acceso root en el sistema, el atacante puede a\u00f1adir un script propio al paquete que se ejecuta autom\u00e1ticamente antes o despu\u00e9s de la instalaci\u00f3n.          <center><img decoding=\"async\" alt=\"Vulnerabilidad en PackageKit que permite obtener derechos de root en diferentes
