Descriptions

The encode_share_access function in fs/nfs/nfs4xdr.c in the Linux kernel before 2.6.29 allows local users to cause a denial of service (BUG and system crash) by using the mknod system call with a pathname on an NFSv4 filesystem.

La función de encode_share_access fs/nfs/nfs4xdr.c en versiones del kernel de Linux anteriores a v2.6.29 permite a usuarios locales provocar una denegación de servicio (caída del sistema) mediante el uso de la llamada al sistema 'mknod' con una ruta de acceso en un sistema de archivos NFSv4.
