CVE-2026-35365

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.

Summary		(es) La utilidad mv en uutils coreutils maneja incorrectamente los árboles de directorios que contienen enlaces simbólicos durante movimientos a través de límites de sistemas de archivos. En lugar de preservar los enlaces simbólicos, la implementación los expande, copiando los destinos enlazados como archivos o directorios reales en el destino. Esto puede llevar al agotamiento de recursos (espacio en disco o tiempo) si los enlaces simbólicos apuntan a directorios externos grandes, a la duplicación inesperada de datos sensibles en ubicaciones no deseadas, o a una recursión infinita y copia repetida en presencia de bucles de enlaces simbólicos.
