(Gentoo Issues Fix) OpenOffice World-Readable Temporary Files Disclose Files to Local Users
SecurityTracker Alert ID:  1011831
SecurityTracker URL:  http://securitytracker.com/id/1011831
CVE Reference:   CVE-2004-0752   (Links to External Site)
Date:  Oct 21 2004
Impact:   Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.1.2
Description:   A vulnerability was reported in OpenOffice. A local user may be able to obtain documents belonging to another local user.

pmladek reported that the software uses insecure temporary files. When started, OpenOffice creates a world-readable temporary directory ('/tmp/sv<RAND>.tmp'). When an OpenOffice file is saved, a compressed version (zip file) is saved in the temporary directory.

A local user can access the temporary directory and obtain the file.

The vendor was notified on August 17, 2004.

Carsten Eiram of Secunia is credited with discovering this flaw.

Impact:   A local user can obtain information belonging to another local user.
Solution:   Gentoo has released a fix and indicates that all affected OpenOffice.org users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=app-office/openoffice-1.1.3"
# emerge ">=app-office/openoffice-1.1.3"

All affected OpenOffice.org binary users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=app-office/openoffice-bin-1.1.3"
# emerge ">=app-office/openoffice-bin-1.1.3"

All affected OpenOffice.org Ximian users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=app-office/openoffice-ximian-1.3.4"
# emerge ">=app-office/openoffice-1.3.4"

Synopsis
========

OpenOffice.org uses insecure temporary files which could allow a
malicious local user to gain knowledge of sensitive information from
other users' documents.

Background
==========

OpenOffice.org is an office productivity suite, including word
processing, spreadsheets, presentations, drawings, data charting,
formula editing, and file conversion facilities.

Affected packages
=================

    -------------------------------------------------------------------

    -------------------------------------------------------------------
  1  app-office/openoffice             == 1.1.2                < 1.1.2
                                                              >= 1.1.3

    -------------------------------------------------------------------
     3 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
===========

On start-up, OpenOffice.org 1.1.2 creates a temporary directory with
insecure permissions. When a document is saved, a compressed copy of it
can be found in that directory.

Impact
======

A malicious local user could obtain the temporary files and thus read
documents belonging to other users.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All affected OpenOffice.org users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=app-office/openoffice-1.1.3"
    # emerge ">=app-office/openoffice-1.1.3"

All affected OpenOffice.org binary users should upgrade to the latest
version:

    # emerge sync

    # emerge -pv ">=app-office/openoffice-bin-1.1.3"
    # emerge ">=app-office/openoffice-bin-1.1.3"

All affected OpenOffice.org Ximian users should upgrade to the latest
version:

    # emerge sync

    # emerge -pv ">=app-office/openoffice-ximian-1.3.4"
    # emerge ">=app-office/openoffice-1.3.4"
