Summary: deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/<block-dev-basename> 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.
Access Authentication: NONE
Access Complexity: MEDIUM
Access Vector: LOCAL
