-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell iPrint Server. Authentication is not
required to exploit this vulnerability. 

The flaw exists within the '/opt/novell/iprint/bin/ipsmd' component this
component communicates with 'ilprsrvd' which listens on TCP port 515.

attacker can exploit this vulnerability to execute arbitrary code under
the context of the iprint user.
