Descriptions

The NFSv4 implementation in the Linux kernel before 3.2.2 does not properly handle bitmap sizes in GETACL replies, which allows remote NFS servers to cause a denial of service (OOPS) by sending an excessive number of bitmap words.

La implementación de NFSv4 en el núcleo de Linux anteriores a v3.2.2 no maneja adecuadamente los tamaños de mapa de bits en las respuestas GETACL, lo que permite a servidores remotos NFS causar una denegación de servicio (oops) mediante el envío de un número excesivo de palabras de mapa de bits.
