Descriptions

fs/ecryptfs/inode.c in the eCryptfs subsystem in the Linux kernel before 2.6.28.1 allows local users to cause a denial of service (fault or memory corruption), or possibly have unspecified other impact, via a readlink call that results in an error, leading to use of a -1 return value as an array index.

El codigo fuente del fichero fs/ecryptfs/inode.c en el subsistema eCryptfs de versiones del kernel de Linux anteriores a la 2.6.28.1 permite a usuarios locales provocar una denegación de servicio (con fallo o corrupción de memoria), o posiblemente tener algún otro impacto no especificado, a través de una llamada a readlink que resulta en un error que provoca un valor de retorno -1 en el indice de un array.
