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 lt; 1.1.4-r1 gt;= 1.1.4-r1
2 app-office/openoffice-bin lt; 1.1.4-r1 gt;= 1.1.4-r1
3 app-office/openoffice-ximian lt; 1.3.9-r1 gt;= 1.3.9-r1
*gt;= 1.3.6-r1
*gt;= 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 "gt;=app-office/openoffice-1.1.4-r1"

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

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=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.
