Synopsis
========

Multiple vulnerabilities have been discovered in OpenOffice.org,
allowing for remote execution of arbitrary code.

Background
==========

OpenOffice.org is an open source office productivity suite, including
word processing, spreadsheet, presentation, drawing, data charting,
formula editing, and file conversion facilities.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/openoffice < 2.1.0-r1 >= 2.1.0-r1
2 app-office/openoffice-bin < 2.2.0 >= 2.2.0
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

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

John Heasman of NGSSoftware has discovered a stack-based buffer
overflow in the StarCalc parser and an input validation error when
processing metacharacters in a link. Also OpenOffice.Org includes code
from libwpd making it vulnerable to heap-based overflows when
converting WordPerfect document tables (GLSA 200704-07).

Impact
======

A remote attacker could entice a user to open a specially crafted
document, possibly leading to execution of arbitrary code with the
rights of the user running OpenOffice.org.

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-2.1.0-r1"

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.2.0"
