Doc Text:
A security issue was found in Rclone. Insecure handling of symlinks with `--links` and `--metadata` while copying to the local disk allows unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files, compromising system integrity, confidentiality, and availability.

Description OSIDB Bzimport 2024-11-15 18:01:48 UTC
Rclone is a command-line program to sync files and directories to and from different cloud storage providers. Insecure handling of symlinks with --links and --metadata in rclone while copying to local disk allows unprivileged users to indirectly modify ownership and permissions on symlink target files when a superuser or privileged process performs a copy. This vulnerability could enable privilege escalation and unauthorized access to critical system files, compromising system integrity, confidentiality, and availability. This vulnerability is fixed in 1.68.2.
