取得元が公開している説明をそのまま載せています (多くは英語)。
deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/ in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.
