Gentoo Linux Security Advisory

Title: LibreOffice: Multiple vulnerabilities (GLSA 201209-05)
Severity: normal
Exploitable: remote
Date: September 24, 2012
Bug(s): #386081, #409455, #416457, #429482
ID: 201209-05

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: app-office/libreoffice
Vulnerable: < 3.5.5.3
Unaffected: >= 3.5.5.3
Architectures: All supported architectures

Package: app-office/libreoffice-bin
Vulnerable: < 3.5.5.3
Unaffected: >= 3.5.5.3
Architectures: 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:
Code:
# 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose
      ">=app-office/libreoffice-bin-3.5.5.3"
