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.

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
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-office/openoffice == 1.1.2 < 1.1.2
>= 1.1.3
2 app-office/openoffice-bin == 1.1.2 < 1.1.2
>= 1.1.3
3 app-office/openoffice-ximian == 1.1.60 < 1.1.60
== 1.1.61 >= 1.3.4
-------------------------------------------------------------------
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"
