______________________________________________________________________________

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.

   - squirrelmail cross site scripting problems

     squirrelmail was updated to fix two cross-site-scripting
     vulnerabilities that can be used by an attacker to read opened
     emails (CVE-2007-1262) and to send email on behalf of the user
     (CVE-2007-2589).

     This problem was fixed for SUSE Linux 10.0, 10.1 and openSUSE 10.2.

   - OpenOffice_org macro virus "BadBunny"

     Since May this year a macro virus for OpenOffice_org is going
     around. The code is mostly harmless and can be classified as a
     proof-of-concept virus.  OpenOffice_org does not execute macros in
     a document per default, the user is asked to enable macros when
     the document is opened.  We encourage users not to enable macros
     from untrusted sources. When you receive a document from a known
     person via email, ask this person first before you open the document.

     More information: http://secunia.com/virus_information/38489/sbbadbunny-a/

   - Blackdown JDK/JRE
     The Blackdown JDK/JRE suffers from the same problems as Sun JDK/JRE,
     like for instance the current image decoding problems.

     In the case of the Blackdown Java implementation there is no update
     package or source-code available, therefore we can not provide
     security updates. If possible switch to Sun's Java package.

     Only SUSE Linux Enterprise Desktop 1.0 contains the Blackdown JDK.

   - gnash denial of service
     A denial of service problem was fixed in the free flash player gnash.
     (CVE-2007-2500)

     gnash is shipped only on openSUSE 10.2 and was fixed there.

   - libpng denial of service

     Applications using libpng can crash if libpng is ask to
     process a grayscale image with a malformed (bad CRC) tRNS
     chunk. (CVE-2007-2445)

     This problem was fixed for all SUSE Linux based distributions.

   - python memory disclosure
     A off-by-one error in the PyLocale_strxfrm() function in python was
     fixed which can lead to a memory information leak. (CVE-2007-2052)

     This has been fixed for all SUSE Linux based products.

   - pulseaudio denial of service
     pulseaudio was updated to fix a denial-of-service bug that can be
     triggered remotely. (CVE-2007-1804)

     Only openSUSE 10.2 contains pulseaudio and is affected by this bug.

   - gd denial of service
     A denial-of-service bug in libgd that can occur while processing
     crafted images was fixed. (CVE-2007-2756)

     This problem has been fixed for all SUSE Linux based distributions.

   - OTRS cross site scripting problem

     A cross site scripting (XSS) vulnerability in OTRS was fixed.
     (CVE-2007-2524).

   - net-snmp denial of service

     This update fixes a denial of service problem which could be
     triggered by a packet containing a single byte. (CVE-2005-2177)

     This problem only affected SUSE Linux 9.3 and 10.0 and was fixed
     for these distributions.
______________________________________________________________________________

2) Pending Vulnerabilities, Solutions, and Work-Arounds

   - Mozilla Firefox 2.0.0.4 update
     The Mozilla Firefox 1.5.0.12 / 2.0.0.4 release fixes various
     security issues.

     We have released updates for all packages, except for SLE10. Once
     this update is out, a full advisory will be released.

   - file security problems

     Additional file security problems were found. Updates have been
     released for all distributions for all but SUSE Linux 10.1 and
     SLE 10. Once updates for these distributions are released, a full
     advisory will follow.

   - freetype2 problems

     TTF related security problems  were fixed in the freetype2
     packages. Packages for all distributions but SUSE Linux 10.1 and
     SLE 10 have been released already.

     Once the latter are released, a full advisory will follow.

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.

  - SUSE runs two security mailing lists to which any interested party may
    subscribe:

    opensuse-security@opensuse.org
        -   General Linux and SUSE security discussion.
            All SUSE security announcements are sent to this list.
