Vulnerability Description
LiME through 1.12.0 fails to validate the disk acquisition output path and does not use O_NOFOLLOW when opening the operator-supplied path parameter, allowing unprivileged local users to overwrite arbitrary root-owned files. An attacker who controls the output directory can create a symbolic link with the expected filename pointing to any root-owned file, and when the acquisition runs in kernel context, LiME follows the link and truncates the target file with the memory acquisition stream.
