        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.

   - RealPlayer security problem

     A RealPlayer security problem was found where a specially crafted
     .rm movie file could overflow a buffer and allow remote attackers
     to execute code in the context of the user running the player.

     We already released a fix with our previous RealPlayer security
     update, check SUSE-SA:2005:059.

     This is tracked by the Mitre CVE ID CVE-2005-2629.

   - giflib,libungif denial of service attack / buffer overflows

     The GIF processing libraries libungif and giflib were updated to
     fix the following security issues:

     - Specially crafted GIF files could crash applications
       (CVE-2005-2974).

     - Specially crafted GIF files could overwrite memory which
       potentially allowed to execute arbitrary code (CVE-2005-3350).

     This affects all SUSE Linux based products.

   - snort overflow in back orifice preprocessor

     A buffer overflow in snort's Back Orifice preprocessor code was
     fixed.  This bug can be exploited by remote attackers to execute
     arbitrary code with the privileges of the snort daemon.

     This is tracked by the Mitre CVE ID CVE-2005-3252.

     All SUSE Linux based products containing snort were affected.

   - clamav buffer overflows

     The clamav virus scan engine was updated to version 0.87.1.
     This upgrade fixes among other things the following security issues:

     - clamav could be made to crash via a malformed DOC file
       (CVE-2005-3239).

     - a buffer overflow in the FSG decoder (CVE-2005-3303).

     - clamav could run into an endless loop due to malformed CAB files
       (CVE-2005-3500, CVE-2005-3501).

     All SUSE Linux based distributions containing clamav were affected.

   - jboss information disclosure

     The default configuration of jboss allows disclosure of sensitive
     information to remote users, by using a GET request with "%." to
     reveal the local installation path, or "%" before a filename to
     reveal the contents of this file.

     We will not release updated packages for this. The jboss group
     recommends disabling the RMIClassLoadingService webservice.

     In all jboss-service.xml files you have, change this snippet:

     <mbean code="org.jboss.web.WebService"
           name="jboss:service=WebService">
           <attribute name="Port">8083</attribute>
           <!-- Should resources and non-EJB classes be downloadable -->
           <attribute name="DownloadServerClasses">true</attribute>
           <attribute name="Host">${jboss.bind.address}</attribute>
           <attribute name="BindAddress">${jboss.bind.address}</attribute>
        </mbean>

     to:

      <!-- Disabled to address CVE-2005-2006
        <mbean code="org.jboss.web.WebService"
           name="jboss:service=WebService">
           <attribute name="Port">8083</attribute>
           <attribute name="DownloadServerClasses">true</attribute>
           <attribute name="Host">${jboss.bind.address}</attribute>
           <attribute name="BindAddress">${jboss.bind.address}</attribute>
        </mbean>
      -->

     This is tracked by the Mitre CVE ID CVE-2005-2006.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - zope

     Zope honors file inclusion directives in RestructuredText objects
     which potentially allowed attackers to execute arbitrary code (Zope
     Hotfix 2005-10-09).

     Updates are currently being QA tested.

     All SUSE LINUX products >= 9.1 and SLES9 are affected.

   - phpMyAdmin cross site scripting and file inclusion problems

     We are preparing updates for the following issues:

     - multiple cross-site scripting (XSS) bugs (CVE-2005-3301,
       CVE-2005-2869, PMASA-2005-5).

     - multiple file inclusion vulnerabilities that allowed an attacker
       to include arbitrary files (CVE-2005-3300, CVE-2005-3301,
       PMASA-2005-5).

     All SUSE LINUX products are affected.

   - libdga format string problem

     libgda contains two format string bugs in logging routines. Those
     bugs could potentially indirectly lead to arbitrary code execution
     via applications that link against libgda and supply data to libgda
     (CVE-2005-2958).

     Updates are currently being QA tested.

     All SUSE LINUX products and SLES9 are affected.

   - php4,php5

     Stefan Esser discovered a cross-site scripting bug in the phpinfo()
     function (CVE-2005-3388), a bug that allows an attacker to enable
     register_globals (CVE-2005-3389) and a bug that allows an attacker
     to overwrite the $GLOBALS array (CVE-2005-3390).

     We are preparing updates for these issues.

     All SUSE LINUX based products are affected.

   - gnump3d various problems
     Steve Kemp discovered a cross-site scripting bug (CVE-2005-3122) and
     a directory traversal bug (CVE-2005-3123) in gnump3d.

     We are preparing updates for these issues.

     All SUSE LINUX products are affected.

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.

    subscribe:
