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	Architecture(s)
app-office/libreoffice	< 3.5.5.3	>= 3.5.5.3	All supported architectures
app-office/libreoffice-bin	< 3.5.5.3	>= 3.5.5.3	All supported architectures

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 --verbose
      ">=app-office/libreoffice-bin-3.5.5.3"
