Synopsis
========
A heap-based buffer overflow vulnerability has been discovered in
OpenOffice.org, allowing for the 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 < 2.3.0 >= 2.3.0
2 app-office/openoffice-bin < 2.3.0 >= 2.3.0
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------
Description
===========
iDefense Labs reported that the TIFF parsing code uses untrusted values
to calculate buffer sizes, which can lead to an integer overflow
resulting in heap-based buffer overflow.
Impact
======
A remote attacker could entice a user to open a specially crafted
document, possibly leading to execution of arbitrary code with the
privileges 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-2.3.0"
All OpenOffice.org binary users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.3.0"
