Package for OOo Security Bulletin 2006-06-29
OpenOffice.org 2.0.3 has been announced as out !
(french version is expected in the coming hours)

This announcement provides a security bulletin dealing with 3 potential vulnerabilities detected by internal security audits.

if you can not install this new 2.0.3 version for whatever reason, the issue dealing with java applet can be countered as mentionned on the Java Applets, CVE-2006-2199 dedicated page
(be carefull that other issues remain !!)

The solution proposed works great by deactivating java applets but is not so easy to deploy at large scale or for regular users. So i used the OOo Tools for what they are made for : The UNO Package concept that allow to create great extensions but also deploy configuration settings

So this addon reproduces what is proposed on the CVE page. It works for OOo 2.x as well as OOo 1.x

To deploy under OOo 2.x
  • Tools > Package Manager > add and select the zip file
    or
  • launch <OOoInstall>/program/unopkg <ZipFilePath>

To deploy under OOo 1.x
  • launch <OOoInstall>/program/pkgchk <ZipFilePath>

Note that running these command lines with the -s switch (for share) let you deploy the addon for all your users

For testing that the patch has been applied correctly, you can insert an applet (eg. the JavaClock.class can be used for testing purpose) and see if it does not run.

You insert a java Applet though
  • Insert > Object > Applet
Once the patch applied, only a drawing with the name of the applet should be displayed and the applet should not run anymore

This check also apply to already created document containing applets

Lettre ouverte au sujet d'OpenDocument
L'appel à commentaire du Réferentiel Général d'Interropérabilité de la DGME touche à sa fin.
Un volet important concerne le format de fichier bureautique et des règles concernant OpenDocument sont proposées et discutées.

L'Alliance OpenDocument, dont Nuxeo est membre, publie une lettre ouverte à destination du Directeur de l'Agence de Modernisation de L'Etat afin de souligner les bénéfices et opportunités du format OpenDocument (ODF) pour l’Administration Française en mettant en avant les gains en terme d'indépendance, d'interopérabilité, d'innovation et préservation de l’héritage culturel entre autres.

OpenDocument est le format de fichier de référence d'OpenOffice.org (et d'autres suites bureautiques) et désormais reconnu par la plateforme CPS

OOoDust : my own "proof of nothing"
Stardust "proof of concept" virus has been announced by an anti-virus editor.
At first, let state one thing : "Macros and extensions, like any program, are active Things and then can hurt"
Once this said, we can not call all macros viruses !
A virus needs to replicate, propagate, most often silently ...

The stardust "thing", does nothing of this. By default OOo asks for every run of a macro and any administrator or user can even disable this feature or restrict macros to some trusted sources directories. The user has to explicitly accept running a program. So nothing to notice there

Among Pavel's announcements with its as usual accurate wordings : only waste of time
Some relay of other anti-virus editors are even more ridiculous as stardust is identified as XML virus under the name XML_DUSTAR: hey, a new beast is born

All of this is restricted to StarOffice, so let me introduce my own OOoDust as a first state of reflexion in building the new malware engines of coming years

sub OOoDust()
print "You're infected"
end sub

to activate it is rather simple

  1. open a new document
  2. open the macro editor (tools > macros > ....)
  3. create a new module
  4. copy the virus in this module
  5. save your document
  6. restart OOo (or send your file to a target)
  7. open your document
  8. agree on activating macro after reading the message
  9. go to macro editor (tools > macro ..)
  10. launch the evil macro OOoDust

It is obvious that OOo and StarOffice will be hurt soon by some malware attacks, but, guys, this not for this time. The dust of this advertisement smoke of anti-virus editors is easily dissipating while examinating the process ...

 Btw, OpenOffice.org project has a structure for reporting any suspicious behaviour, so feel free to contact us
As stated in the official OOo first reaction
"the consistent message from security experts [is] that users should never accept files from unknown sources".
