        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.

   - 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).

     All SUSE LINUX products and SLES9 were affected.

   - flash-player buffer overflow

     flash-player has been updated to version 7.0.25 to fix a buffer
     overflow (CVE-2005-2628).

     Only SUSE Linux 9.0 and 9.1 are affected by this problem.

   - gpsdrive format string problem

     gpsdrive was updated to fix the following security problem: A format
     string bug in friendsd2 allowed an attacker to execute arbitrary code
     (CVE-2005-3523).

     This affects SUSE Linux 9.0 up to 10.0.

   - squid various denial of service attacks

     Two denial of service attacks against the web proxy Squid were fixed:

     - A bug in the NTLM authentication could crash Squid (CVE-2005-2917)
     - Odd replies of FTP servers could crash Squid (CVE-2005-3258)

     This affects all SUSE Linux based products including Squid.

   - spamassassin denial of service

     The spam detection program spamassassin could be crashed by a very
     long recipient lists in a mail's "To:" header.

     This is tracked by the Mitre CVE ID CVE-2005-3351.

     Only SUSE Linux 9.2 up to 10.0 are affected by this problem.

   - mediawiki cross site scripting attack

     MediaWiki was updated to fix the following security problem: Unsafe
     handling of CSS by Microsoft Internet Explorer could be exploited
     to produce cross-site scripting attacks via Javascript injection
     to clients running that browser (CVE-2005-3167).

     This problem affects SUSE Linux 9.3 and 10.0.

   - zope potential remote code execution

     The content management system Zope has been updated to fix the
     following security problem: Zope honors file inclusion directives
     in RestructuredText objects which potentially allowed attackers to
     execute arbitrary code (Zope Hotfix 2005-10-09).

     This is tracked by the Mitre CVE ID CVE-2005-3323.

     All SUSE Linux versions including Zope are affected by this problem.

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - 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.
