Who is Vulnerable?
Vulnerability Description	The Novell Netware operating system as well as various other Novell products contain numerous components which serve to provide various capabilities and services. One such component is the Novell Distributed Printing Services (NDPS) component which provides extended printing facilities that enables clients to control a printer device in a more effective way. This is implemented through the NDPS protocol, which, in addition, may be used to distribute printer resources among client hosts as needed. There exists an integer overflow vulnerability in Novell Distributed Print Services module in multiple Novell products. The vulnerability is caused due to lack of proper boundary checks prior to the calculation of the size of a memory buffer. An unauthenticated attacker may exploit this vulnerability to inject and execute arbitrary code in the context of the vulnerable application, Super User in the Netware systems. Successful exploitation of this vulnerability may allow the flow of the process to be diverted to an arbitrary location. In such a case, the behavior of the target host will be completely dependent on the intention of the injected code. In case of an unsuccessful attack, the Novell Distributed Print Services will terminate, causing a denial of service condition. To restore the functionality, the application or service must be restarted manually.
