      "value": "The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use (TOCTOU) race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create(), which internally uses O_TRUNC. An attacker can exploit this window to create a file or swap a symlink at the target path, causing touch to truncate an existing file and leading to permanent data loss."

      "value": "La utilidad touch en uutils coreutils es vulnerable a una condición de carrera Time-of-Check to Time-of-Use (TOCTOU) durante la creación de archivos. Cuando la utilidad identifica una ruta faltante, más tarde intenta la creación usando File::create(), que utiliza internamente O_TRUNC. Un atacante puede explotar esta ventana para crear un archivo o intercambiar un enlace simbólico en la ruta de destino, haciendo que touch trunque un archivo existente y lo que lleva a la pérdida permanente de datos."
