"The version of LibreOffice installed on the remote Mac OS X host is 
earlier than 3.3.3 / 3.4.0.  As such, it is reportedly affected by a 
stack buffer overflow in the Lotus Word Pro import filter that arises 
from its failure to properly handle object ids in '.lwp' documents. 

If an attacker can trick a user on the affected system into importing
a specially crafted .lwp document into the application, he could
leverage this issue to execute arbitrary code subject to the user's
privileges."
