3) Technical details
============================
 
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell Groupwise
 
Internet Agent where IMAP services run. Authentication is required to exploit this vulnerability.
 
The flaw exists within the IMAP functionality included with GWIA. When provided with an overly long LIST or LSUB request
to the CREATE verb, the IMAP server can be forced to overflow a buffer on the stack. Successful exploitation leads to
 
remote code execution under the context of the server.
