Synopsis
========

OpenOffice.Org is vulnerable to a heap overflow when processing DOC
documents, which could lead to arbitrary code execution.

Background
==========

OpenOffice.org is an office productivity suite, including word
processing, spreadsheets, presentations, drawings, data charting,
formula editing, and file conversion facilities.

Affected packages
=================

    -------------------------------------------------------------------
     Package                       /  Vulnerable  /         Unaffected
    -------------------------------------------------------------------
  1  app-office/openoffice            < 1.1.4-r1           >= 1.1.4-r1
  2  app-office/openoffice-bin        < 1.1.4-r1           >= 1.1.4-r1
  3  app-office/openoffice-ximian     < 1.3.9-r1           >= 1.3.9-r1
                                                          *>= 1.3.6-r1
                                                          *>= 1.3.7-r1
    -------------------------------------------------------------------
     3 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

AD-LAB has discovered a heap overflow in the "StgCompObjStream::Load()"
function when processing DOC documents.

Impact
======

An attacker could design a malicious DOC document containing a
specially crafted header which, when processed by OpenOffice.Org, would
result in the execution of arbitrary code with the rights of the user
running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All OpenOffice.Org users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-1.1.4-r1"

All OpenOffice.Org binary users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-1.1.4-r1"

All OpenOffice.Org Ximian users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose app-office/openoffice-ximian

Note to PPC users: There is no fixed OpenOffice.Org binary version for
the PPC architecture yet. Affected users are encouraged to switch to
the latest OpenOffice.Org source package.

Note to SPARC users: There is no stable OpenOffice.Org fixed version
for the SPARC architecture. Affected users should switch to the latest
OpenOffice.Org Ximian version.
