Vulnerability Description	Novell GroupWise is a client-server collaborative software and email system provided by Novell. The Novell GroupWise Client application is capable of communicating with Novell Group server, as well as Internet email gateways using SMTP, POP, and IMAP protocols. There exists a stack buffer overflow vulnerability in the Novell GroupWise. The vulnerability is due to a boundary error while processing specially crafted SMTP request. Remote attackers can exploit this vulnerability to execute arbitrary code on the target server. In an attack case where code injection is successful, the behaviour of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute with the security privileges of the server. In an attack case where code injection is not successful, the affected process will terminate abnormally.
