Summary

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.

Risk Assessment

An attacker can use a symbolic link to overwrite or truncate critical system files, potentially leading to system integrity compromise or denial of service.

Recommendation

Update LiME to the latest patched version. Also ensure the acquisition output directory is only writable by trusted users.

Original NVD description (English source)

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.
