The nfs_permission function in fs/nfs/dir.c in the NFS client
implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open
is available, does not check execute (aka EXEC or MAY_EXEC) permission
bits, which allows local users to bypass permissions and execute files, as
demonstrated by files on an NFSv4 fileserver.
