This script is Copyright (C) 2002-2016 Tenable Network Security, Inc.

Synopsis :

The identd server is prone to a remote buffer overflow attack.

Description :

The identd server on this port seems to be a version of fake identd
that fails to properly validate user input before copying it into a
buffer of fixed size. By splitting data into two or more packets, an
anonymous remote attacker can overflow the input buffer and execute
arbitrary code with root privileges.
