        3) Authenticity Verification and Additional Information

______________________________________________________________________________

1) Solved Security Vulnerabilities

   To avoid flooding mailing lists with SUSE Security Announcements for minor
   issues, SUSE Security releases weekly summary reports for the low profile
   vulnerability fixes. The SUSE Security Summary Reports do not list md5 sums
   or download URLs like the SUSE Security Announcements that are released for
   more severe vulnerabilities.

   Fixed packages for the following incidents are already available on our FTP
   server and via the YaST Online Update.

   - fbi unsafe postscript display
     The fbgs program did not activate security options in the postscript
     interpreter due to a typo (CVE-2006-3119). fbgs also used a temporary
     directory with a predictable name (CVE-2006-1695).

     Updates have been released for all SUSE Linux products.

   - gimp XCF loader problem
     A buffer overflow was fixed in the xcf loader in GIMP that allows
     user-complicit attackers to cause a denial of service (crash) and
     possibly to execute arbitrary code via an XCF file with a large
     num_axes value in the VECTORS property. (CVE-2006-3404)

     Fixed gimp and gimp-unstable packages have been released for all
     SUSE Linux based products.

   - libwmf overflow
     A heap overflow could be triggered by specially crafted WMF (Windows
     Meta Files) in the libwmf library. This problem could be exploited
     to execute code, by a remote attacker providing a file with embedded
     WMF data to an application understanding this (like OpenOffice_org,
     abiword, gimp).

     This issue is tracked by the Mitre CVE ID CVE-2006-3376 and affects
     all SUSE Linux based products.

   - X.org server PCF problems
     The PCF handling in the X.Org and XFree86 servers suffered from
     similar problems than freetype2. This security update fixes crashes
     in the PCF handling, which might be used to crash the Xserver using
     applications or even to execute code in it.

     All SUSE Linux based products were affected by this problem.

   - zope information disclosure
     The content management system Zope had a bug in the way the
     docutils module parses and renders "restructured text" could lead
     to information disclosure.

     This issue is tracked by the Mitre CVE ID CVE-2006-3458 and affects
     all SUSE Linux products.

   - horde various problems

     The following two security issues were fixed in the Horde Application
     Framework:

     - CVE-2006-3548: Multiple cross-site scripting (XSS) vulnerabilities
       allow remote attackers to inject arbitrary web script or HTML
       via a (1) javascript URI or an external (2) http, (3) https, or
       (4) ftp URI in the url parameter in services/go.php (aka the
       dereferrer), (5) a javascript URI in the module parameter in
       services/help (aka the help viewer), and (6) the name parameter
       in services/problem.php (aka the problem reporting screen).

     - CVE-2006-3549: services/go.php does not properly restrict its
       image proxy capability, which allows remote attackers to perform
       "Web tunneling" attacks and use the server as a proxy via (1)
       http, (2) https, and (3) ftp URL in the url parameter, which is
       requested from the server.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - Kernel Update for Enterprise Distributions

     The update kernels for the last 2 local root privilege escalations
     are still not released due to trouble with (mandatory) partner
     re-certification testing.

     We hope to be able to release them this week.

   - Mozilla Firefox / Thunderbird / Suite Security Updates

     We will be updating Mozilla in the next days.

     - Mozilla Firefox:

       All Mozilla Firefox on released distributions will be upgraded
       to version 1.5.0.6.
       This update affects: Novell Linux Desktop 9, SUSE Linux Enterprise 10,
       SUSE Linux 9.2 - 10.1

       The update might break manually installed Firefox Extensions.

     - Mozilla Thunderbird

       Mozilla Thunderbird updates have been released, the version
       was bumped to 1.5.0.5. (The patch summary lists it incorrectly
       at 1.5.0.6, but it is 1.5.0.5)

     - Mozilla Suite discontinuation / replacement by Seamonkey.

       Since the Mozilla Suite is no longer maintained, we will replace
       it by Seamonkey 1.0.3.

       This update affects: SUSE Linux Desktop 1, SUSE Linux Enterprise
       Server 8, SUSE Linux Enterprise Server 9, Novell Linux Desktop 9,
       SUSE Linux 9.2 - 10.0.

       This will likely also require updates of evolution, beagle,
       and other dependent packages, so it might take some time.

       In general we recommend not using the Mozilla Suite any longer.

    - php4 / php5 security updates in preparation

      A critical PHP 4 / 5 problem was found, we are preparing updates
      for this problem. (CVE-2006-4020)

    - ethereal security update

      The last ethereal security update is currently being tested in QA.

3) Authenticity Verification and Additional Information

  - Announcement authenticity verification:

    SUSE security announcements are published via mailing lists and on Web
    sites. The authenticity and integrity of a SUSE security announcement is
    guaranteed by a cryptographic signature in each announcement. All SUSE
    security announcements are published with a valid signature.

    To verify the signature of the announcement, save it as text into a file
    and run the command

      gpg --verify <file>

    replacing <file> with the name of the file containing the announcement.
    The output for a valid signature looks like:

      gpg: Signature made <DATE> using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team <security@suse.de>"

    where <DATE> is replaced by the date the document was signed.

    If the security team's key is not contained in your key ring, you can
    import it from the first installation CD. To import the key, use the
    command

      gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc

  - Package authenticity verification:

    SUSE update packages are available on many mirror FTP servers all over the
    world. While this service is considered valuable and important to the free
    and open source software community, the authenticity and integrity of a
    package needs to be verified to ensure that it has not been tampered with.

    The internal RPM package signatures provide an easy way to verify the
    authenticity of an RPM package. Use the command

      rpm -v --checksig <file.rpm>

    to verify the signature of the package, replacing <file.rpm> with the
    filename of the RPM package downloaded. The package is unmodified if it
    contains a valid signature from build@suse.de with the key ID 9C800ACA.

    This key is automatically imported into the RPM database (on RPMv4-based
    distributions) and the gpg key ring of 'root' during installation. You can
    also find it on the first installation CD and included at the end of this
    announcement.
