  Overview: The host is installed OpenOffice and is prone to multiple remote
  heap based buffer overflow vulnerabilities.

  Vulnerability Insight:
  Error in 'WMF' and 'EMR' records in 'EMF' files may allow a remote unprivileged
  user who provides a 'StarOffice/StarSuite' document that is opened by a local
  user to execute arbitrary commands. These can be exploited to cause heap buffer
  overflow.

  Impact:
  Successful exploitation will allow execution of arbitrary code with the
  privileges of the current user.
  
  Impact Level: System

  Affected Software/OS:
  - OpenOffice.org OpenOffice verions prior to 2.4.2

  Fix: Upgrade to OpenOffice version 2.4.2 or later
