______________________________________________________________________________

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 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.

   - moodle cross-site scripting and cross-site request forgery problems

     An incorrect input validation in moodle could be exploited by
     remote attackers to inject arbitrary script code or to forge 
     HTTP requests (CVE-2008-3325, CVE-2008-3326).

     moodle is contained in and was fixed for openSUSE 10.2, 10.3 and 11.0.

   - Opera 9.51 fixes memory issues

     Opera did not properly manage memory within functions supporting
     the CANVAS element. This allowed attackers to read unintitialized
     memory contents using malicious JavaScript code (CVE-2008-3078). 

     Opera is contained in and was fixed for openSUSE 10.2, 10.3 and 11.0

   - libxcrypt wrong password encryption

     libxcrypt did not encrypt passwords with MD5 when it was selected
     in its configuration file, instead it always used DES as password
     encryption algorithm (CVE-2008-3188).

     Only libxcrypt in openSUSE 11 was affected by the issue and fixed.

   - acroread unspecified vulnerability

     An unspecified vulnerability in acroread allowed remote attackers to 
     cause a denial-of-service or possibly execute arbitrary code via 
     unknown vectors. (CVE-2008-2641).

     acroread was fixed for openSUSE 10.2 and 10.3

   - gnumeric integer overflows

     Due to integer signedness errors it was possible for attackers     to execute arbitrary code by the use of specially crafted XLS files
     (CVE-2008-0668).

     gnumeric was fixed for openSUSE 10.2 and 10.3

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 

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

      gpg: Signature made  using RSA key ID 3D25D3D9
      gpg: Good signature from "SuSE Security Team "

    where  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 

    to verify the signature of the package, replacing  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.
