  3) Technical details
  ============================
  
  This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations 
  of Novell Groupwise Internet Agent. Authentication is not required to exploit this vulnerability.
  
  The flaw exists within the IMAP server component which listens by default on TCP port 143. When
  handling an IMAP LIST command with a large parameter the process attempts to free the same memory
  twice. A remote attacker can exploit this vulnerability to execute arbitrary code under the 
  context of the IMAP server.
