______________________________________________________________________________

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.

   - phpMyAdmin XSS problems and SQL injection

     phpMyAdmin was updated to fix the following security problems:
     - Multiple cross-site-scripting bugs (CVE-2006-1803, CVE-2006-1678)

     - A bug that allows to inject arbitrary SQL commands (CVE-2006-1804)

     SUSE Linux versions 9.1 up to 10.0 are affected.

   - asterisk integer overflow in JPEG handling

     The PBX software asterisk had insufficient length checks when
     processing JPG files that allowed attackers to overflow a buffer.

     This issue is tracked by the Mitre CVE ID CVE-2006-1827 and affects
     SUSE Linux 9.2, 9.3 and 10.0.

   - libtiff various denial of service attacks

     This update of libtiff fixes several bugs that can lead to a remote
     denial-of-service attack. To trigger this bug the user has to use an
     application that uses libtiff to process malformed TIFF images.
     (CVE-2006-2024, CVE-2006-2025, CVE-2006-2026)

   - beagle potential command injection

     The beagle indexing daemon invokes commands to extract meta or
     textual data from files in an insecure way, allowing injection of
     additional program options. This was fixed by a security update.

     SUSE Linux 9.3 and 10.0 are affected and the issue is tracked by
     the Mitre CVE ID CVE-2006-1865.

   - horde XSS and file exposure

     This update fixes the following security issues in the Horde
     framework:

     - Insufficient input validation of an URL parameter allowed
       attackers to read arbitrary files (CVE-2006-1260).

     - Multiple cross-site-scripting bugs (CVE-2005-4190)

     This affects all SUSE Linux based products.

   - dia xfig handling problems

     Multiple buffer overflows in the xfig import routines of dia can
     be used by user-complicit attackers to potentially execute code as
     the user.

     This issue is tracked by the Mitre CVE ID CVE-2006-1550.

     It affects SUSE Linux 9.2 up to 10.0 and Novell Linux Desktop 9.

   - openvpn remote code execution

     When connecting via openvpn to malicious openvpn servers it was
     possible for the remote server to push environment variables like
     for instance LD_PRELOAD or similar to the client, making it possible
     for remote attackers to execute code.

     This issue is tracked by the Mitre CVE ID CVE-2006-1629.

     SUSE Linux 9.3 and 10.0 are affected by this problem.

   None are listed this week.

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.
