Descriptions

Off-by-one error in the build_unc_path_to_root function in fs/cifs/connect.c in the Linux kernel before 3.9.6 allows remote attackers to cause a denial of service (memory corruption and system crash) via a DFS share mount operation that triggers use of an unexpected DFS referral name length.

Error de superación de límite (off-by-one) en la función build_unc_path_to_root en fs/cifs/connect.c en Linux kernel anterior a v3.9.6 permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria y caída del sistema) a través de una operación de montaje DFS compartido lo que provoca el uso de un DFS inesperado referido a la longitud del nombre.
