Synopsis
========
A truncation error and integer overflows in the EMF/WMF file handling
of OpenOffice.org could be exploited to execute 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-bin < 2.1.0 >= 2.1.0
2 app-office/openoffice < 2.0.4 >= 2.0.4
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
John Heasman of NGSSoftware has discovered integer overflows in the
EMR_POLYPOLYGON and EMR_POLYPOLYGON16 processing and an error within
the handling of META_ESCAPE records.
Impact
======
An attacker could exploit these vulnerabilities to cause heap overflows
and potentially execute arbitrary code with the privileges of the user
running OpenOffice.org by enticing the user to open a document
containing a malicious WMF/EMF file.
Workaround
==========
There is no known workaround known at this time.
Resolution
==========
All OpenOffice.org binary users should update to version 2.1.0 or
later:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.1.0"
All OpenOffice.org users should update to version 2.0.4 or later:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/openoffice-2.0.4"
