Synopsis

A flaw in the client service for NetWare may allow an attacker to execute arbitrary code on the remote host.

Description

The remote host contains a version of the Client Service for NetWare that is vulnerable to a buffer overflow. An attacker may exploit this to cause a denial of service by sending a malformed IPX packet to the remote host, or to execute arbitrary code by exploiting a flaw in the NetWare client.

Solution

Microsoft has released a set of patches for Windows 2000, XP and 2003.
