Descriptions

deepin-clone before 1.1.3 uses a fixed path /tmp/repo.iso in the BootDoctor::fix() function to download an ISO file, and follows symlinks there. An unprivileged user can prepare a symlink attack there to create or overwrite files in arbitrary file system locations. The content is not attacker controlled. By winning a race condition to replace the /tmp/repo.iso symlink by an attacker controlled ISO file, further privilege escalation may be possible.

deepin-clone anterior a versión 1.1.3, utiliza una ruta (path) fija /tmp/repo.iso en la función BootDoctor::fix() para descargar un archivo ISO, y sigue ahí los enlaces simbólicos (symlinks). Un usuario sin privilegios puede preparar en esta ubicación un ataque de enlace simbólico para crear o sobrescribir archivos en ubicaciones del sistema de archivos arbitrarias. El contenido no es controlado por el atacante. Al ganar una condición de carrera para reemplazar el enlace simbólico /tmp/repo.iso mediante un archivo ISO controlado por un atacante, puede ser posible una escalada de privilegios mayor .
