    {

      "value": "A race condition was found in the mkhomedir tool shipped with the oddjob package in versions before 0.34.5 and 0.34.6 wherein, during the home creation, mkhomedir copies the /etc/skel directory into the newly created home and changes its ownership to the home's user without properly checking the homedir path. This flaw allows an attacker to leverage this issue by creating a symlink point to a target folder, which then has its ownership transferred to the new home directory's unprivileged user."

      "value": "Se encontr\u00f3 una condici\u00f3n de carrera en la herramienta mkhomedir enviada con el paquete oddjob en versiones anteriores a 0.34.5 y 0.34.6 en la que, durante la creaci\u00f3n del inicio, mkhomedir copia el directorio /etc/skel en el inicio recientemente creado y cambia su propiedad al usuario del inicio sin comprobar apropiadamente la ruta homedir. Este fallo permite a un atacante aprovechar este problema al crear un punto de enlace simb\u00f3lico en una carpeta de destino, que luego ha transferido su propiedad al usuario no privilegiado del nuevo directorio de inicio."
