-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell eDirectory. Exploitation does not
require authentication.

default exposes an HTTP interface on TCP port 8028 and an HTTPS
interface on TCP port 8030. During the parsing of long URIs to the
'nds' path a trivially exploitable stack-based buffer overflow occurs.
