OVERVIEW:

        OpenOffice.org have released version 2.4 fixing multiple 
        vulnerabilities. [1]


IMPACT: 

        Each of the vulnerabilities fixed may result in the execution of 
        arbitrary code.  The specific vulnerabilities remedied by this 
        release are as follows:

        "A security vulnerability with the way OpenOffice.org 2 
         processes ODF text documents with XForms, using the 3rd
         party library ICU, may allow a remote unprivileged user 
         who provides a OpenOffice.org document that is opened by
         a local user to execute arbitrary commands on the system 
         with the privileges of the user running OpenOffice.org.
         No working exploit is known right now." [2]

        "A security vulnerability with the way OpenOffice.org 2 
         processes Quattro Pro files may allow a remote unprivileged 
         user who provides a OpenOffice.org document that is opened
         by a local user to execute arbitrary commands on the system
         with the privileges of the user running OpenOffice.org.
         No working exploit is known right now." [3]

	"A security vulnerability with the way OpenOffice.org 1.1 
         and 2 process EMF files may allow a remote unprivileged
         user who provides a OpenOffice.org document that is opened
         by a local user to execute arbitrary commands on the system
         with the privileges of the user running OpenOffice.org.
         No working exploit is known right now." [4]

        "A security vulnerability with the way OpenOffice.org 1.1 
         and 2 process OLE files may allow a remote unprivileged
         user who provides a OpenOffice.org document that is opened
         by a local user to execute arbitrary commands on the system
         with the privileges of the user running OpenOffice.org.
         No working exploit is known right now." [5]


MITIGATION:

         OpenOffice.Org advise that there is no workaround for these 
         vulnerabilities and users are advised to upgrade to version 
         2.4 [6].
