A vulnerability exists in the Novell GroupWise Messenger Client (GWIM) for Windows that could allow an attacker to execute arbitrary code on a compromised workstation. The vulnerability takes the form of a remote buffer overflow in the client, caused by spoofed server responses to valid client requests. All versions of the Windows client, prior to the patch for this issue, are vulnerable.
