______________________________________________________________________________

1) Problem Description and Brief Discussion

   Various problems have been fixed in the network analyzer Ethereal (now called
   Wireshark), most of them leading to crashes of the ethereal program.

   CVE-2006-5740: An unspecified vulnerability in the LDAP dissector
   could be used to crash Ethereal.

   CVE-2006-4574: A single \0 byte heap overflow was fixed in the MIME multipart
   dissector. Potential of exploitability is unknown, but considered low.

   CVE-2006-4805: A denial of service problem in the XOT dissector can cause
   it to take up huge amount of memory and crash ethereal.

   CVE-2006-5469: The WBXML dissector could be used to crash ethereal.

   CVE-2006-5468: A NULL pointer dereference in the HTTP dissector could
   crash ethereal.

2) Solution or Work-Around

   There is no known workaround, please install the update packages.

3) Special Instructions and Notes

   None.

4) Package Location and Checksums

   The preferred method for installing security updates is to use the YaST
   Online Update (YOU) tool. YOU detects which updates are required and
   automatically performs the necessary steps to verify and install them.
   Alternatively, download the update packages for your distribution manually
   and verify their integrity by the methods listed in Section 6 of this
   announcement. Then install the packages using the command

     rpm -Fhv 

   to apply the update, replacing  with the filename of the
   downloaded RPM package.

6) 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 where you saved 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 the integrity of
    a package needs to be verified to ensure that it has not been tampered
    with.

    There are two verification methods that can be used independently from
    each other to prove the authenticity of a downloaded file or RPM package:

    1) Using the internal gpg signatures of the rpm package
    2) MD5 checksums as provided in this announcement

    1) 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 at
       the end of this announcement.

    2) If you need an alternative means of verification, use the md5sum
       command to verify the authenticity of the packages. Execute the command

         md5sum 

       after you downloaded the file from a SUSE FTP server or its mirrors.
       Then compare the resulting md5sum with the one that is listed in the
       SUSE security announcement. Because the announcement containing the
       checksums is cryptographically signed (by security@suse.de), the
       checksums show proof of the authenticity of the package if the
       signature of the announcement is valid. Note that the md5 sums
       published in the SUSE Security Announcements are valid for the
       respective packages only. Newer versions of these packages cannot be
       verified.
