Who is Vulnerable?
Vulnerability Description Novell GroupWise Messenger is a corporate instant messaging solution targeting toward medium to large enterprise organizations. It facilitates secure communications and policy-based management through Novell's eDirectory product suite. The product is based on a client-server model where messaging clients connect to a central server to communicate after successful authentication is performed. A buffer overflow vulnerability exists in Novell GroupWise Messenger product. The flaw is due to an improper handling of crafted HTTP responses. An unauthenticated remote attacker can exploit this vulnerability by sending spoofed HTTP responses to the target host. Successful attack could allow for arbitrary code execution with privileges of the currently logged in user. In case of an attack where code injection is not successful, the affected application will terminate. In case of an attack where code injection and execution is successful, the behavior of the target host is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the current user.
