If you cannot patch yet, avoid moving directory trees containing symbolic links across filesystem boundaries using this utility or use alternative tools that correctly preserve symlinks.

Description

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-h444-6j9x-p8vh. This link is maintained to preserve external references. ### Original Description The mv utility in uutils coreutils improperly handles directory trees containing symbolic links during moves across filesystem boundaries. Instead of preserving symlinks, the implementation expands them, copying the linked targets as real files or directories at the destination. This can lead to resource exhaustion (disk space or time) if symlinks point to large external directories, unexpected duplication of sensitive data into unintended locations, or infinite recursion and repeated copying in the presence of symlink loops.
