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.
