    SSRT3613 rev.0 HP-UX B6848AB GTK+ Support Libraries
                   elevated privileges

     The information in this Security bulletin should be acted upon
     as soon as possible.

    INITIAL RELEASE: 10 May 2004

    POTENTIAL SECURITY IMPACT: elevated privileges for a local
                                  authorized user.

                    HP Software Security Response Team



    A potential vulnerability has been identified with HP-UX running
    B6848AB GTK+ Support Libraries where a directory permissions issue
    could be exploited to allow a local authorized user to gain
    elevated privileges.

    SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
    HP-UX B.11.00, B.11.11 with B6848AB GTK+ Support Libraries

         The product B6848AB (GTK+ Libraries) is available for
        download from software.hp.com:

        < http://www.software.hp.com/cgi-bin/swdepot_parser.cgi/cgi/

        The source files in this product are world writable.
        After the product is installed any user can modify the
        source. If new libraries are to be built using this
        source code the files should be verified.

        The web page above has the following description of B6848AB:

          The GTK+ Libraries are the open source GNU toolkit for X
          windows development. The version provided here is
          unsupported, but is provided for use with the unsupported
          Mozilla browser for 10.20 and for old versions of Netscape
          (i.e. 6.2.1), which depend on it. We recommend upgrading to
          a newer browser/OS combo, such as Mozilla for HP-UX 11.0
          and later, which require a newer version of the GTK.

        Note: Product B6848BA (ximian gnome 1.4 gtk+ libraries for
              hp-ux) does NOT have this permissions problem.


         Note: To determine if a system has an affected version,
               search the output of "swlist -a revision -l fileset"
               for an affected fileset. Then determine if the
               recommended patch or update is installed.

         HP-UX B.11.00
         HP-UX B.11.11
          action: remove (optionally reinstall and change perms)
                  install revision or subsequent.

          action: remove (optionally reinstall and change perms)
                  install revision or subsequent.


        Note: The directory permissions are secure in all versions
              of B6848BA. However, only B6848BA revision 1.4.gm.46
              or subsequent resolves the permissions issue for
              directories installed by B6848AB.

        Note: B6848AB is only required for Netscape 6, which is no
                  longer supported on HP-UX. The recommended
                  solution is HP's Mozilla (www.hp.com/go/mozilla),
                  which requires B6848BA.

        If B6848BA is needed:

        1. Remove B6848AB.
           This removes any potentially altered source files.
           However, the directories remain with unsafe permissions.

        2. Install B6848BA revision 1.4.gm.46 or subsequent.
           This corrects the directory permissions.

        3. Reinstall B6848AB if it is needed.

        If B6848BA is not needed and B6848AB is needed.

        1. Remove B6848AB.

        2. Reinstall B6848AB.

        3. Immediately make the following changes to directory

             chmod 555 /opt/gnome/src/GLib/glib-1.2.8
             chmod 555 /opt/gnome/src/GLib/glib-1.2.8/docs

    To review previously published Security Bulletins for HP-UX:

    The HP-UX Security Patch Matrix is available here:
    Or via anonymous ftp:

    The HP-UX Security Patch Matrix, updated daily, categorizes
    security patches by platform/OS release, and by Bulletin topic.
    The Security Patch Check tool completely automates the process of
    reviewing the Security Patch Matrix for HP-UX 11.XX Versions.
    NOTE: Installing patches listed in the Security Patch Matrix will
    completely implement the RESOLUTION in the Security Bulletin
    _only_ if there are no MANUAL ACTIONS included.

    The Security Patch Check tool can also verify that a Security
    Bulletin RESOLUTION has been implemented on HP-UX 11.XX Versions
    provided that no MANUAL ACTIONS were included. The Security Patch
    Check tool cannot verify patches implemented via product upgrade.

    For information on the Security Patch Check tool, see:
