Descriptions

The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.

Las funciones (1) real_lookup y (2) __lookup_hash en el archivo fs/namei.c en la implementación de vfs en el kernel de Linux anterior a versión 2.6.25.15 no previene la creación de una matriz de elementos secundarios para un directorio eliminado (también se conoce como S_DEAD), que permite a los usuarios locales causar una denegación de servicio ("overflow" del área huérfana UBIFS) por medio de una serie de intentos de creación de archivos sin eliminar los directorios.
