Synopsis
========
Multiple vulnerabilities have been found in LibreOffice, allowing
remote attackers to execute arbitrary code or cause a Denial of
Service.

Background
==========
LibreOffice is a full office productivity suite.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/libreoffice < 3.5.5.3 >= 3.5.5.3
2 app-office/libreoffice-bin
< 3.5.5.3 >= 3.5.5.3
-------------------------------------------------------------------
2 affected packages

Description
===========
Multiple vulnerabilities have been found in LibreOffice:

* The Microsoft Word Document parser contains an out-of-bounds read
error (CVE-2011-2713).
* The Raptor RDF parser contains an XML External Entity expansion error
(CVE-2012-0037).
* The graphic loading parser contains an integer overflow error which
could cause a heap-based buffer overflow (CVE-2012-1149).
* Multiple errors in the XML manifest handling code could cause a
heap-based buffer overflow (CVE-2012-2665).

Impact
======
A remote attacker could entice a user to open a specially crafted
document file using LibreOffice, possibly resulting in execution of
arbitrary code with the privileges of the process or a Denial of
Service condition.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All LibreOffice users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/libreoffice-3.5.5.3"=

All users of the LibreOffice binary package should upgrade to the
latest version:

# emerge --sync
# emerge --ask --oneshot -v ">=app-office/libreoffice-bin-3.5.5.3"
